I got all excited when I saw your comment and went and checked out the latest RubyMine video on YouTube, because having something like Firebug for Ruby would be awesome. But it looks just like what gdb gives you when being driven by a graphical frontend like DDD or Emacs. Actually it looks a lot less powerful than DDD. What am I missing?

That's not for the go team to develop.

I haven't used RubyMine, but I have used Visual Studio and Eclipse debuggers, and I still debug using gdb, ruby-debug, pdb et al.
