That could be true. But the real reasons I use Coffee script are the features it adds to the language: list comprehensions, splats, existential operator, severely concise class syntax. And I don't see this offering any features that are as useful as those. The Snow code looks uglier, I think, than the PHP code. But if it looked uglier and gave me extra features (like, for instance, splats, comprihensions, improved slicing and range syntax, etc), I'd still probably use it.
