Hi there,
The old PIR subroutine attributes ("method", "@MULTI", "@MAIN", "@LOAD",
"@IMMEDIATE", "@POSTCOMP", and "@ANON") are now deprecated in favor of the
lowercased colon-prefixed version. (At least, that's what the code appears
to say.)
A lot of the test suite and much of the library still uses the old form. I've
applied the following patch to the lexer and rebuild Parrot (run Configure.pl
with the --maintainer flag) to remove this code. Now you can run the tests
and the libraries to find the old attributes to update.
(Allison mentioned earlier today that she saw a difference in strict argument
checking between the "method" and ":method" forms. I can't verify that, but
this is an easy todo item for someone just getting started.)
This patch is definitely not suitable for application before the upcoming
release. I have patches to make Parrot finish building after applying the
patch and regenerating IMCC, but I'll hold off on those for a while too.
