Yes... everyone talked briefly, then went off and wrote their own
grammars separately.  I had hoped for a more collaborative effort...

Part of that's my fault, I guess, since I was holding the bag for key
things like grammar unit tests and never followed through because I got
too busy with other things.

But, the important thing is that the grammars did get written, and in
particular yours is quite complete.

rubyfront is ANTLR 2, isn't it?  If so, do you plan on porting it to
ANTLR 3?  If not, it might be a worthwhile exercise for the project to
either port yours to ANTLR 3, or expand Sara's grammar using yours as a
reference.

Either way, the original plan was to write an ANTLR 3 reference grammar,
and then use that as a basis for a formal specification of Ruby's
grammar.  I think it's still a relevant goal.

Are folks still interested?
