[C++-sig] How about class_<...>.enable_copy() ?

I often use copy.[deep]copy() to copy python objects / BPL-exported types.
This works if pickling support has been explicitly coded, by pickling and
unpickling. It would be neat if there was an .enable_copy() or sth. like
that, which would define a __copy__ (or __deepcopy__) method that simply
calls the copy constructor. That would be more efficient than the pickling
approach, both at runtime and in terms of saved LOCs. Have you thought about
such a thing? Is there a common short idiom that does that already? Is
there a rationale for not providing copying support?
