I'd be interested, especially in one that allowed inheritance of grammars, as
in antlr, and allowing the lex part of the parser being another parser. I've currently
got some smalltalk around somewhere that did analysis of grammers to rm
left recursion an some other ops on grammars. So, yes I'm interested.
