Perl 6: Managing breakages across Rakudo versions

Patrick Michaud, Rakudo lead dev, wants to know what Perl 6 stability policy should be. Or at least, how would you like to see the Rakudo team manage breakages across versions in the near term?

Discuss on the perl6 compiler list (http://www.nntp.perl.org/group/perl.perl6.compiler/2012/07/msg8279.html) or the #perl6 IRC channel on freenode.
