Bug reports should be sent to “firstname.lastname@example.org” with the moniker [BUG](including the brackets) at the start of the subject so that it gets appropriately tagged in the RT system. Please include or attach any sample source code that exhibits the bug, and include either the release name/date or the git commit identifier. You find that information in the output from perl6 –version (or in the first line of git log, if Rakudo fails to build). There’s no need to cc: the perl6-compiler mailing list, as the RT system will handle this on its own.
We use Perl’s RT system (http://rt.perl.org/) for our issue and bug tracking system. Some shortcut links for various reports in RT:
