I did, a few moments later. doing that stuff in irb isn't always as  
easy as doing it in TextMate (note to self).
I like irb because I can just ask objects questions. But irb needs  
more flexibility (the ability to step into and out of writing a block  
to check something else, that would be useful) Access to all the  
running stuff and ability to change it while running. Oh.
