[Haskell-cafe] Haskell vs Ruby as a scripting language

Is anyone using Haskell as a scripting language in their app? I'm thinking of viable it would be to embed ghc in a Mac (Cocoa) app. TextMate [1] uses Ruby as the extension language and quite successfully at that. Everybody loves Ruby since it's simple. I need a trading systems language and I'm afraid the combination of ... everything that makes Haskell otherwise great will prove a drawback in my case. What do you think?
