Grammar with string interpolation confuses kotlin compiler

[jayv]

I'm new to antlr, so perhaps I'm doing something wrong. I'm trying to write a grammar for a language with string interpolation like kotlin by starting from the MiniCalc example. Changing INTERPOLATION_OPEN from #{ into ${ it seems to generate invalid kotlin code:

LITERAL_NAMES list contains "'${'" I suppose this needs escaping in the code generator or is there another way around this? I'd be happy to contribute if pointed in the right direction.
