2. signature() function support all kinds of callables: classes, metaclasses, methods, class- & staticmethods, 'functools.partials', and callable objects.  If a callable object has a 'signature' attribute it does a deepcopy of it before return.

Properly decorated functions are also supported. - Yury

This is really exciting! A couple questions/points:

Why do we look at wrapped only if the object is a FunctionType? Why not support wrapped on all callables?

Why special-case functools.partial? Couldn't functools.partial just set signature itself? Is that because of inspect's dependency on functools?

Just a thought: Do we want to include the docstring? A function's docstring is often intimately tied to its signature. (Or at least, a lot of us try to write docstrings that effectively describe the function's signature)
