For those who are interested in adding some of the Perl 6 builtins to Rakudo's core settings files -- I've created a wiki page that lists some prime candidates that I think ought to be relatively easy to convert (perhaps using inline PIR).
http://wiki.github.com/rakudo/rakudo/setting-candidates See also the file "docs/guide_to_setting.pod" in the Rakudo repository. At present I'm still heavily favoring patches submitted via RT over those submitted via the fork queue on github. Pm
