And in the past, I blogged about various quirks of Perl parsing. Unlike
the code from my experiments with parsing Perl, those blog posts would
be (IMHO) worth looking at. -- jeffrey

More seriously, I have one suggestion for anyone thinking of
writing a Marpa-powered Perl grammar. I made a start at it, and
it's in the test suite. Do *NOT* bother looking at it. It's
based on an older, pre-events Marpa, and it is best not to waste
time on it and to make a fresh start from the YACC grammar in the
Perl source.

The grammar you linked to apparently does not guide the parsing -- it's used
to implement an interface. -- jeffrey
Yes, right. PPI is used for rperl, and the guide is just for the API
overview.
Marpa would be faster, but we don't have a perl grammar for marpa yet.
I'm counting on you, guys.
Also for p2, where I had to write my incomplete perl grammar from scratch

Sound heaviily Marpa compatible - but is that really Marpa behind - somebody
knows?
