I've not investigated ANTLR, but you're right, my primary goal was a nice, clean, cocoa-like API in pure Obj-C only API. The only comparable API that I know of is ParseKit which uses recursive decent, and hence doesn't support a lot of grammars. By comparison there, I support SLR, LR(1) and LALR(1), so there's rather more coverage.
I'd really appreciate you taking a look and reporting back if you find any interesting things that ANTLR or other tools does better.
Thanks
