Ruby is a killer language, and I hate to even ask, but:

Would it be possible, sometime in the future, for Ruby to try a .rb
extension on a given filename? That way we could say:
ruby myfile
and myfile.rb would load and run. Myfile.rb would have the .rb extension so
that emacs would know it's a Ruby file.

Would it be possible to modify the emacs mode so that things like:
puts "That will cost you some $"
and others wouldn't fool the syntax highlighter?

Just some thoughts,
  JJ
