With a fast parsing algorithm, you could parse as a programmer types, unlike the current syntax highlighting editors which use only rough pattern matching instead of having a real parse tree. Imagine seeing syntax errors the moment you type them.

That's what Xcode 4 does with the new Clang/LLVM machinery inside.
