We use doctests in a few exercises to ensure some code doesn't compile with the
compile_failattribute. This is not possible with normal unit or integration tests. Examples include the exercisemacros, where the tests ensure the user's macro rejects invalid input, anddoubly-linked-list, where the tests ensure the user doesn't unsoundly implement theSendandSynctraits.
