Hi, t/oo/value_types.t mentions the "is value" trait, which doesn't appear in the spec anywhere. According to the discussion in [1] there was speculation about 'is cow' and 'is value', but the former didn't seem to enter the spec either.
So what should I do about that test? Simply delete it? Moritz [1]: http://groups.google.com/group/perl.perl6.language/browse_thread/thread/afe5ce7665d8c7cb/6c3faa387b62e872
