Resolution: not this Christmas. Short discussion: http://irclog.perlgeek.de/perl6/2015-12-16#i_11729677 In my view, the best hope of doing this is probably through some static analysis, which we can introduce conditional on language version, so it'd be opt in by language version and we'd be able to not break existing code that didn't opt in to using that version. For the meantime, the ticket survives, but is off the xmas list.
