To hopefully clarify it a bit further, in bison one can specify with %union the list of possible types of the token objects, and with %token <TYPE> x that token x is an object of type TYPE. Is there some way to do this in antlr (specifying the type of the token objects on a per-token basis, instead of one single type for all tokens like TokenLabelType does)?
