This is correct -- the "official" grammar (STD.pm) is in pugs.
However, Rakudo's grammar follows STD.pm as closely as it can and
is reasonably close for most things. We'd definitely be interested
to know about any places it's falling short.

OTOH, Rakudo can be used to check syntax (at least as much as
it knows about) by using the --target=parse option.
$ parrot perl6.pbc --target=parse [file]
And we'd be really happy to try out any code fragments you may
have and see if we can get them to parse and execute. We like
it when we can get something new to work. :-) For example,
the infix // operator and @*ARGS were added to Rakudo in direct
response to Aaron Trevena wanting to get the Towers of Hanoi
example [1] running.
Specific questions or problems with Rakudo should probably
go to [EMAIL PROTECTED], or find a Rakudo developer on
#parrot or #perl6. And bug reports can be filed at
<[EMAIL PROTECTED]>.
Thanks!
