I generally lean towards returning the undecorated function, so that if you say:

Oops, forgot to mention: one other advantage to returning the undecorated function is that you can do this:
@func.register(int)
@func.register(float)
def do_num(foo):
...Which neatly solves the multiple registration problem, even without argument annotations.
