Depends. Equality of what? Equality of lexical items *is* the business of the parser (actually of the lexicalizer, if that terminology is acceptable here). So this depends, seems to me, on whether or not literals are considered to be lexical/syntactic thingies, or only semantic thingies. In the MT I assumed they were syntactic, and left open the issue of what they denote (could be themselves, of course).
