in reply to Stumped when passing barewords

I'm surprised you're not getting the dreaded "prototype too late" warning. That may be the real bug here. 
use strict;
use warnings;
foo(2,3,4);
sub foo($$$) { print "@_", $/ }
__OUTPUT__
main::foo() called too early to check prototype at - line 3.

    This is because in your example the call to foo can be discerned at compile-time, whereas subroutine calls within other subroutines can't due to perl's dynamic nature, hence the lack of use strict 'subs must exist'.
