I my code I'm always making sure that string variables are set to a value. If they are set I do something, if they are blank, I do something else. Pretty typical.

I'm trying to increase my skillz to go beyond this type of checking: 

if ($foo eq "") {
   #do something kool
}
else {
   #do something not so kool
}

I'm thinking that a regexp could be used?
Thanks a lot for your insight!
