        Depends on how you want to code.  Running the irb inferior and
zapping lines and loading files into irb is very lisp/REPL- y.  You
can run ruby files via emacs compile command.  Without any
modification, you can issue the compile command( m-x compile is one 1)
and then replace the default make command with your ruby command,
i.e. ruby -w foo.rb.  It wil run the file in a *compilation* buffer
that among other things can allow you to jump to both compile and
runtime errors.  I've hacked up mode-compile.el to recognize ruby
(larging by cutting pasting the perl entries and replace perl w/ruby).
What compile mode does is try to intelligently look at the current
buffer and apply the right "compiler"
