IOW, why can't we use (functionp keywords) instead of (fboundp keywords)? In principle, I don't see why matchers can't be lambda expressions. The main concern I have is that other parts of font lock might have subtle assumptions about the matcher being a function name. It seems easier to make this implicit assumption an explicit one.
