Thanks - I agree that's a good approach for a lot of cases, but lambdas
can only be simple expressions and ANTLR generates code with some cases
that raise exceptions or break or nest switch statements, so
unfortunately dictionaries of lambdas can't handle everything that
ANTLR's generated code needs to do.
