I'm using Switch with a series of pattern matches. Inside the case statement, I need to use $1($2, etc) from my pattern match. However, $1 isn't changing after the match. Is there something else I can use to access $1 or do I need to re-match inside the case statement? example: 
switch ($val) {
case /^\s*(\S+)$/{
print "$1\n";
}

I ended up just preserving $1 inside are var before the switch. I've never had a problem using Switch, and for this code (sorry, can't post it) I have a several nested if's inside of each case. I'll test it again and see if removing the switch improves performance.
