<sloth> if i have something like my ( $a,$b ) = ($foo =~ /hello(bar)?world(flop)/);
<sloth> will $a be empty, undefined or what $b would be assuming there is no bar?
<pink_mist> don't use $a or $b
<pink_mist> except in sort blocks
<pink_mist> not even in examples
<sloth> then $foo and $bar
<pink_mist> you already had $foo there
<sloth> then $pink and $mist
<gry> :D
