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:
arg = f()
# ... whatever ...
This is exactly the obvious way to spell "f() is called every time stuff()
Keeping medicines from the bloodstreams of the sick; food
from the bellies of the hungry; books from the hands of the
uneducated; technology from the underdeveloped; and putting
advocates of freedom in prisons. Intellectual property is
to the 21st century what the slave trade was to the 16th.
