Hmm, I'm not sure here. It may be harder to do, but wouldn't it be better to let ```parse_simple_selector()``` decide that it didn't actually parse anything? For example, pass in a flag that says "either you find something, or it's a syntax error"? It's only used in three places, and two of them need that decision now. (And the third looks like the author wasn't sure if it's needed ...)
