What is wrong with:
def called(arg):
if arg == True:
return True
.
.
return False
def caller(arg)
if called(arg):
return 1
return 2
If you like different return values, something like:
return (True, <other values>)
in called() and
shortcut, <return values> = called(arg)
if shortcut:
return <return values>
in caller() works for me.
As Malcolm mentioned, throwing an exception might be another good way
to do things.
Or did I miss the point of what you're trying to do?
