In the simple case, that's already done. Just use *a,**kw, and the wraps(f) decorator will mark it as "use the signature of that function over there". Unfortunately, that's only the simple case. You can't say "use the signature of that function, but I also accept this arg". You can't say "use the signature of that function, except that I don't accept this arg". But it would be theoretically possible to do exactly that using basically the inspect module, and it would be an extremely useful feature for many situations, especially if it can be automated in some way (eg if it notices "def f(spam, *a, **kw)" and adds spam to the parameter list).
