inspect.getfullargspec is currently unable to introspect builtin functions and methods. Should builtins gain a signature so they can be introspected? If function signatures are useful, then they're useful, and the implementation language for the function is irrelevant. I already sent Yuri a patch adding signature to PyCFunctionObject, which I thought he merged but I don't see in his repo.

I would love to be able to inspect builtins for their signature. I have a class decorator that needs to know the signature of the class constructor, which unfortunately falls down for the simple cases of inheriting from a builtin without a custom init or new.
