Matz:

I'm not agreeing or disagreeing, but just curious. What would be wrong
with a reference implementation of the Ruby parser in Ruby? Assuming
it would be simpler to work with, it would give us a platform from
which to experiment with various language options. It would also be
invaluable to writers of tools such as rubydoc. Of course we'd end up
maintaining two parsers, but if they were both derived from a common
source, such as ANTLR, that might not be so bad.
