Previously '=' was not included in our PUNCTUATION regeular expression, but it *was* excldued from our OTHER regular expression, so we were getting the default (and hamful) lex action of just printing it. The test we add here is named "punctuator" with the idea that we can extend it as needed for other punctuator testing.
