I had to confirm what $x=!!$y meant in perl. Remarkably, typing !! or
"!!" or \!\! into google gives you nothing. Had to use English.
The +42 answer is quite good. Exec summary: !! is good for cleaning vars
into 1 (true) or '' (false), which is important to keep warnings from
complaining about undef vars.
Anyhow, read the comments in the +42 answer. Hehehe.
Let the flamewars begin!
