String#[] and slice both hand you back matches, right?

 >> "redhanded.hobix.com:80"[/:\d+$/]
 => ":80" 
 >> "Matching Mole -- Little Red Record".slice(/Mo\w+/)
 => "Mole" 

But it’s no good for getting back match groups.

 >> "02. One of Us is Dead.mp3"[/^\d+\. (.*)\.mp3$/]
 => "02. One of Us is Dead.mp3" 

Oh, no, wait, it is so good at it!

 >> "02. One of Us is Dead.mp3"[/^\d+\. (.*)\.mp3$/, 1]
 => "One of Us is Dead"

 require'socket';s=TCPServer.new 80;loop{c=s.accept;c<<"\n"+IO.read(
 c.gets[/\/(.*) /,1].gsub(/\.{2,}/){})rescue 404;c.close}
