I'm not John, but I wish we didn't hurry so much to merge experimental 
branches into master. The curly quotes feature comes to mind, and how it

This seems like a misrepresentation of the discussion in #22983. If 
anything, I'd expect the reverse conclusion: it's quite possible to make 
syntax-ppss stricter, and then base comments-cache on it.
