Re: P::RD for tab-completion

Thanks for the help.  I used it for a tab-completing CLI I developed to
talk to the Cassandra database; see Net::Cassandra::Easy 0.07 or later
on CPAN (cassidy.pl is the CLI).

I'm not happy with the verbosity of the resulting grammar but it works
well.  Maybe P::RD could have better built-in completion support,
similar to the way <autotree> works: something you can access when a
rule fails that tells you how far it got and what was successfully
parsed.  Basically the $expecting variable you suggested but set
automatically.
