This doesn't make sense. Function definition time is very different than
function execution time. Changing that distinction is a WAY bigger change
than I think we should contemplate.
Moreover, there is a completely obvious way to spell the behavior you want:
def stuff():
arg = f()
# ... whatever ...
This is exactly the obvious way to spell "f() is called every time stuff()
is".
