rofl aamazing, ty very much :)

had a feeling i was complicating things.


does it work as well for building bigger applications(not just
webapps), like building an editor like emacs. is the language as
suitable for that?
i know executionspeed is the issue with ruby and python but thats not
really an issue and will be even less of one in the future i guess.

must be some tradeoff no?


anyway ty for the help, the rubycommunity seems very nice and helpful!
