At present the grammar engine is able to load entire sets of
rules, organize them into grammars, and allow rules to be
created using either Perl 6 rule syntax or as custom PIR
-subroutines. The next immediate steps are to (1) design the
-grammar engine so that the p6rule parser is itself a callable
-rule, to make it possible to parse rule expressions within Perl
-programs, and (2) create a parser that parses Perl 6 programs
-into Match objects.
+subroutines. The grammar engine also provides callable
+rules for parsing rule expressions (using Perl 6 rule
+syntax, Perl 5 regular expression syntax, or wildcard
+globs). There is also some preliminary work being done
+on creating parsers from grammars in BNF syntax.

+A preliminary Perl 6 parser has also been created with
+PGE and is being extended to cover more of the Perl 6
+language; the parser is currently held in the
+languages/perl6/ directory of the Parrot repository.
