I have a function which is intended for use at the interactive interpreter,

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.
E.g.
def func():
do_stuff()
if procedure: # FIXME what goes here???
return "Awesome"
else:
return 999
Now I can do this:
x = func()
assert x == 999
L = [1, 2, func(), 4]
assert L[2] == 999
func()
# 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?
Probably. ;)
But it it solve a problem, why not.
Best,
Sven
