but may sometimes be used non-interactively. I wish to change it's output
depending on the context of how it is being called.
If the function is being called as if it were a procedure or command, that
is the return result is just ignored, I want to return one thing. But if it
is being called where the return result goes somewhere, I want to return
something else. Most importantly, I don't want to pass a flag to the
function myself, I want the function to know its own context.
I don't mind if it is CPython only, or if it is a bit expensive.
if procedure: # FIXME what goes here???
Now I can do this:
x = func()
assert x == 999
L = [1, 2, func(), 4]
assert L == 999
# interactive interpreter prints "Awesome"
Is such a thing possible, and if so, how would I do it?
If I did this thing, would people follow me down the street booing and
jeering and throwing things at me?
