Hmm, now that I look at this again, I'm not sure whether ! qualifies as an operator. It might be better off being in the delimeters list? @pablogsal What do you think?

It's certainly not an operator. I would include in the delimiter list for sure. It's very similar to the ":" in the sense that it separates two parts, it doesn't apply to any or both of them
