Re x 2: Can I tell a sub to take $_ instead of @

About your line:

    my $parm = $_[0] || $_;

What is you call this?

test(0);
test("");

You should wait for Perl 6 and use the new operator //.

<tongue-in-cheek> Printing a null byte to the screen isn't very useful anyway! It's a feature:) </tongue-in-cheek> `my $parm = defined $_[0] ? $_[0] : $_;`? What's this about a "crooked mitre"? I'm good at woodwork!	[reply] [d/l]
