Preserve function signature with decorator

[Wyko]

I've noticed that my IDE (VS Code) does not show the function arguments of anything decorated by the @cached decorator. It would be great if the decorator would fully preserve the function's signature.

Does #512 really match the question? Talking about typing vs preserving the original function signature.

You're showing type annotations from your IDE. We don't have complete type annotations (or any exposed at all), so your IDE won't give you the correct types.
