It would be Objective-C and Haskell, the exact split yet unknown.

You already have this in HOC (http://hoc.sourceforge.net/)

I don't see how this is different from Ruby.

I'm not sure this would apply to me as I'm on Mac OSX.

Well, yes, I would want syntax highlighting and formatting. I would,  
in fact, need a built-in Haskell IDE.

I would want to compile code as well. Compile bits of code <100 lines  
at a time and load them back into my app for execution. Does YHC  
compile and how efficiently?
