That would be really nice, but CoffeeScript will probably not be adding types unless they start adding them to JavaScript.

It is a dilemma, but so far I have gotten by without type-checking.

Well, guess it's time for someone to build yet another layer of abstraction by writing a typed superset that compiles-to-CoffeeScript then!

(I'm joking, but actually.. why not?)

call it ToffeeScript - a dialect of CoffeeScript that transpiles to TypeScript?

I'm afraid you're a few years too late!
