I don't understand that argument.
We can implement late-bound defaults right now, using the usual sentinel jiggery-pokery.
def func(spam, eggs, cheese=None, aardvark=42): if cheese is None: ... # You know the drill.
We can wrap functions like this. You don't generally even care what the sentinel is. A typical wrapper function looks something like this:
@functools.wraps(func) def inner(*args, **kwargs): # wrapper implementation func(*args, **kwargs)
with appropriate pre-processing or post-processing as needed.
Why would argument unpacking to call the wrapped function stop working?
