Re: Force caller to return

The answer is no. Even throwing an exception from argok() can be easily defeated: the called subroutine has first dibs on catching exceptions.

But since you are in control of argok(), can't you just collect the information you want in argok()?

The information is collected in argok(). The information collected there should be returned to the caller of the method/subroutine that uses Argpass, not the user of those methods/subroutines. I would also prefer not to muddy the user code with conditional returns, and ideally to avoid using exceptions. I'm not completely surprised that this isn't possible though.	[reply]
