lobstr::obj_addr

[scipima]

quick question,
in exercise Q2, section 1.1, why don't i get the same address if I pass the list of mean function as argument of lapply/map?

in other words, if i run
lapply(list(mean, base::mean, get("mean"), evalq(mean), match.fun("mean")), lobstr::obj_addr)
the object address is not the same.
