Hi,
When testing some 'real world' code using pypy, an inconsistancy with
the way __init__ works between lists and dicts.
The assumption was made when implementing __init__ for pypy that
list.__init__ and dict.__init__ would both wipe the contents of the
objects, but it seems that in cpython, this isn't precisely the case.
>>> l = [2,3]
>>> list.__init__(l)
>>> l
[]
>>> d = {2: 3}
>>> dict.__init__(d)
>>> d
{2: 3}
dict.__init__(mydict) does not wipe the keys. list.__init__(mylist)
wipes the lists contents.

Is there a good reason for this behaviour? It has broken my code (a
subclass of dict that populates a key before calling the superclasses
constructer, in the twisted codebase).
