Nope, you had it right.

Visitor thoroughly confuses me in the context of parsing (maybe in all contexts.)

visit and accept are not the verbs I want to be seeing in the code. I want to see then, or, and try.

Parsers "accept" or "reject" programs. It's completely standard language.

Alright, so where can I read more about the visitor pattern's "reject" method?
