in thread Perl 5.20.0

If you're referring to RT#121975, it seems that between Perl 5.19.11 and 5.20.0, some of the COW improvements stopped working on some platforms (including Darwin). However, the worst case scenario for this bug seems to be that Perl 5.20 "suffers" from 5.18-like performance.

I'm now using Perl 5.20.0 as my main development platform (and have been since yesterday) and so far haven't experienced any problems with it. This includes having installed things like Moose, LWP::UserAgent, RDF::Trine, etc which have lot of dependencies and pretty big test suites.

use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name

    That's not surprising. Every stable Perl version is tested against all of CPAN before release.
