Thanks for the advice.

Well, if I wanted to use a language with rich mathematical symbol 
support, I would use Sun's Fortress, which allows any unicode character. 
But that language is scheduled to be released by 2010, if it gets 
released. An interpreter is available though.

But I'll stick to Haskell ;-)
