[wingide-users] Pickling modules with `copy_reg`

[cool-RR]

I am trying to use the `copy_reg` module to teach the pickle module how to
pickle modules:

'''
def reduce_module(module):
    return (__import__, (module.__name__, {}, {}, ['']))

copy_reg.pickle(types.ModuleType, reduce_module)
'''

This works when I run it normally, but when I run it under debug in Wing, I
get:

'''pickle.PicklingError: Can't pickle <built-in function
wingdb_import_hook>: it's not found as tdbgtracer26.wingdb_import_hook'''

I think what happens is that Python is able to pickle `__import__`, but not
the hook that replaces it in the debugger.

What should I do?
