Is this question a red herring, Guido? Surely one would ask for both copy()
and deepcopy(), the same functions exposed by the copy module. Of course,
I'm not convinced having them as builtins solves the real problem. (Which is
why I asked if the question was a red herring.) If anything, having these
functions as builtins might lead to an excessive use of copying by the same
individuals who hadn't yet gotten a handle on mutable versus immutable
objects.
