It's unclear to me what `Void` is meant to provide in your example. Is your hope for a `Void` value to not be passed as a parameter to the wrapped function?

Hello, I'll give an example:

def func_wrapper(..., param="default"):

We have to duplicate value of parameter "default" if we want to use this as the default. Or we can do that:

def func(param="default"):
    ...

def func_wrapper(..., *args):
   ...
   func(*args)

But it won't always be possible. In addition, auto-completion in IDEs won't work.
It would be cool to have an empty type like Void (not None) for explicit full control:

def func(param="default"):
    ...

def func_wrapper(..., param=Void):
   ...
   func(param)
