RoR "goto" function?

What's the goto function for Ruby on Rails?
Something like this:
x: y
if z goto x

Obviously that's not the proper syntax, but I don't know what is. :(

Lol, if your application is small it doesn't matter, if it's big, hopefully it's generating enough ???profit that you can throw more hardware at it.  Optionally you can use a less mature framework like Django, but whatever.

Also bytecode eventually.
