I'm fascinated by this question.

What would be a reason to desire to enforce a void context for a Perl subroutine return value?

As noted in wantarray: `return unless defined wantarray; # don't bother doing more my @a = complex_calculation(); return wantarray ? @a : "@a";` [download] Perhaps the OP is using a function that uses that strategy.	[reply] [d/l]

That is detection not enforcement ... language barrier?	[reply]

If there is a `sub foo` that uses the above method of detecting when it is called in void context so that it can do less work; then that would be a reason the caller of `sub foo` (docdurdee) might want to enforce void context on it.	[reply] [d/l] [select]
