[Python-3000] Nix dict.copy()

[Raymond Hettinger]

Where did we end-up on dict.copy()?

Is the copy(obj) function sufficiently universal to replace the obj.copy() method used in sets and in dict imitators?  Or does the 
need for import preclude it from consideration?

To me it seems that relationship between __copy__ and the copy() function is just as universal as the relationship between __len__ 
and len(). Am I missing something that makes d.copy() preferable to copy(d)?

I don't think we'll ever get another chance to clean-up the mapping API and to remove duplicate functionality (the code for 
dict.__copy__ and dict.copy share the same implementation).
