No description provided.

…lds as python does compiled `==` asks the type rather than answering true for identical objects, tagged ints handle the short minimum and literals too wide to tag, the handled exception survives a re-raise and an except clause's class evaluation, a with block looks its methods up on the type, a name's value is released when the name is rebound, an instance made without __init__ has no fields, comparisons used as values keep the object their method returned, a second import hands back the first module object, and a float subclass goes to the interpreted definition. also releases temporaries at their last read, stores closure cells natively and speeds up big tagged ints

…ave as python's state objects collected from creation and refused construction from python, throw/close/athrow with python's arguments and wording, delegation through yield from and await, a running frame refused, the RuntimeWarning for a coroutine never awaited, weak references, generator expressions and lambdas inside a resumable frame, finally blocks on the exception path, and a traceback entry for each compiled frame an exception passes

a compiled call notices a module function rebound, deleted or patched from outside, and honours a reassigned __code__ or defaults; a compiled recursion counts against the recursion limit and the thread's stack. compile.bind-functions-early and compile.follow-recursion-limit turn each back off, and the development docs say what each leaves

…run python add an analysis of which operations can run python code over the native call graph, and use it to ask once, on the way into a loop, whether a builtin or module function still stands and whether an int field is set; read an extended class's fields through one licence per class

fill every slot python gives a dunder's name, carry members the module body rewrites after the class statement onto the emitted type, keep an attribute that shares a method's name in the instance dict, give instances a weak reference list on python's terms, hand interpreted subclasses an allocator that marks int fields unset, and fix delegation, parked loop iterators and generator expression evaluation order in generators

step a generator directly from a for loop with its state number as a machine integer and its iternext inlined, recycle finished generators' memory, release tagged int temporaries at their last read, borrow list elements across an unbox, hold loop counters as machine integers inside a loop copy, convert counters straight to doubles, unswitch nested loops, and follow python's float floor division, remainder and power case for case

…d checks methods bind through PyMethod_New and answer their def, module, qualname, defaults, annotations and repr as the interpreted function does, class and static methods are wrapped as a class statement wraps them, tp_new is left to object, class patterns read fields only where the layout is held, and a compiled module makes the interpreted build's soundness checks in the same places and words

emit the copy a versioned recursion falls back to as a function of its own, drop a type test an earlier guard already answered, memoize global reads and the soundness check per type and class, answer equality from the right operand's type, build displays from borrowed operands, stop leaking a reference on every compiled int return, and empty a moved-from register with its declared value

@OverRide

…on, and add inherit_ov and loops_aug rows bench.py stages only the source a leg builds from so .by rows build again, the benchmark programs are annotated as their docstrings say, and the sweep renderer prints a compiled method as a callable. cdiff scopes a by.h change definition by definition and writes its summary into its output file, ci runs the scoper's tests, and two benchmark rows measure @OverRide and augmented assignment against their plain siblings

an expression region carries the declarations a statement expression makes instead of asserting it has none, an overload set and a valueless Final are checked in a scope whose end is unreachable, and a class with a gradual base answers as having a gradual member

…eated `_` positional-only re-emit only the nodes an AST pass rewrote and pass the source of the rest through, keeping comments, indentation, clause-line bodies and docstrings, and report the author's own text for f-string and t-string fields. the splice refuses any edit it leaves out unless the pass covering it declares it writes that lowering. a repeated `_` is numbered past every name the module spells, positional-only, and named after an overridden method's parameters, decided once in ty and read by the transpiler, callable types and inline protocols included. `decorator def` gets real overloads, a context parameter is filled through an overload set that agrees on it, a module binding a runtime helper's name is reported, and by run compiles each staged module under its .by path and lines

…runtime evaluates for it version checks run for .by files except where the lowering removes the syntax; an evaluated `|` is `Union` below 3.10 and `T?` a tuple of classes in isinstance; a `some` parameter is a TypeVar at every version, refused off a parameter annotation and on variadics; the generics polyfill imports its constructors and declares its type variables under names the module does not spell and passes ParamSpec and TypeVarTuple defaults through; by run compiles from text so 3.9-3.11 do not recurse, and a -W error warning names the .by line; polyfill runtime tests run on an interpreter that can run them

…facility typing names, builtins, runtime helper names and module-level private symbols are imported or declared under names the module does not bind; one decision names each polyfilled type parameter for the polyfill, inline protocols and anonymous named tuples; the isinstance classinfo decision is one query ty and the transpiler share; method type variables are declared at module scope; a data class gets its slots below 3.10; keyword-pack defaults follow PEP 696

… relate guards by the parameter they narrow, and quote annotations once a protected or private rename onto a name the class hierarchy stores is invalid-visibility; `x is int?` parses the marker as part of the type and `?` over a value types as the `| None` it evaluates; a return guard's target is a type position, `-> a is not T` is refused, and callable types may return a guard, related by which parameter each narrows. a forward reference is not quoted again under the future import, synthesized annotations import with the module's other imports, imported backing functions and conversion targets are bound under per-module names, synthesized classes are named once per module by shape, and a private class-body type alias is a private member. a symbolic fold inside a tuple or callable type is written by the pass that replaces it, and a fold may name a type parameter bound where it is written

…and read repeated `_` names from ty an int register carries a bool or int subclass as the object, asking its own methods for truthiness, unary operators and mixed float arithmetic; unary `+` asks any operand's __pos__; a literal default a place cannot hold as itself goes to the twin; an augmented assignment's slow path asks the in-place method; compiled repeated `_` parameters are named and made positional-only from ty's answer; a float subclass narrowed to its value is documented

…and slot data classes methods marked override, final or abstractmethod compile, and the report counts what really runs; a method the class body binds again publishes what it bound; a module body that writes over a compiled class's members leaves the module interpreted; one decision says which classes are mutable, including a written __new__; a data class declares its slots, publishes __slots__ and its pickling state, and is compared against the class its decorators produced; __class__ reads the defining class; the header compiles below 3.13
