Subject: Weaken the $metaclass closed over by the meta method.
X-Git-Tag: 2.0500~7
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=gitmo%2FMoose.git;a=commitdiff_plain;h=c21e08da2330901dee2d52eb96eaa48670c578bf

Weaken the $metaclass closed over by the meta method.

This breaks some cycles (notably in anon metaclasses, where it actually
matters).
