Actually, because of Haxe's platform-agnostic approach, it can be applied to game developing, file manipulation, command-line tools, GUIs, web servers, encryption, encoding/decoding tools and much more!
I don't see your point, any programming language is platform-agnostic by definition - though code (including standard libraries, although those are usually.. well.. standard) that calls specific system API's may not be. And while perfect cross-platform support sounds nice, sometimes it isn't a requirement (while often desirable).
Found these in some of the code snippet samples, "Neko target only", "#if flash", so much for being platform-agnostic

To be fair the language syntax looks a lot like Java, too, which I guess is a good thing but ultimately makes it yet another class-based language, and I think we have enough of those around already; what we need is a paradigm shift!
EDIT: just so there's no confusion, I'm not "hating on Haxe" or anything, just disagreeing with your statement and making some quick personal observations.
