[New-bugs-announce] [issue1515] deepcopy doesn't copy instance methods

New submission from Michael Van Biesbrouck:

Currently, using deepcopy on instance methods causes an exception to be
thrown.  This can be fixed by adding one line to copy.py:

d[types.MethodType] = _deepcopy_atomic

This will not make duplicate copies of mutable values referenced within
the instance method (such as its associated instance), but it will be
the same as the handling of other function types (which have the same
problem).
