You can easily achieve this with something like

Void = object()

def func(param=Void):

  if param is Void:

    param = "default"


or in the wrapper:

Void = object()

def wrapper(param=Void, **kwargs):

  if param is not Void:

    kwargs["param"] = param

  return func(**kwargs)

With some extra work, you can even create a decorator to handle this automatically.

Yes, I want that when Void is received in a function parameter it is not processed:

func(Void) == func() == "default"
