In general, anything within {} is target language code 
(statements), anything in {}? is a target language expression, and 
anything in [] is sort-of-target-languagey parameter lists ("sort 
of", because ANTLR expects a specific format which might not be 
how the target language usually works).  Anything else is language 
syntax (rule definitions) and isn't target-specific.
