Hi, t/oo/value_types.t mentions the "is value" trait, which doesn't appear in the spec anywhere. According to the discussion in  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 : http://groups.google.com/group/perl.perl6.language/browse_thread/thread/afe5ce7665d8c7cb/6c3faa387b62e872
