For loops there is break, next, and redo. For general unwinding there are exceptions (ie. begin-rescue/ensure/else) and catch-throw pairs (not to be confused with exceptions). There are also delimited continuations (via callcc), though I doubt you will need this feature. Finally, what I recommend in most of these cases is refactoring. While goto can be a very clear way to describe things, it is a rare occasion. It is even more rare that another alternative ruby provides isn't at least as clear. If you can provide an idea of what you are thinking you need goto for, go ahead and post some code and ruby-talk can hammer it out into a beautiful master piece. If you still really want to have goto, I think there is a library that emulates label based jumps... check RAA or Rubyforge. Brian.
