[issue15373] copy.copy() does not properly copy os.environment

[R. David Murray]

R. David Murray <rdmurray at bitdance.com> added the comment:

os.environ is not a dictionary, so it isn't all that surprising that a shallow copy doesn't behave like a shallow copy of a dictionary.  deepcopy does what you'd expect, as does os.environ.copy().

Perhaps it is worth improving this by adding a __copy__ method to os.environ.  Someone would need to propose a patch, and it would be an enhancement.
