$ ./perl6 -e 'say 3.isa(Mu:U)' True That's not the right answer for what I want Mu:U to do. Actually the attempt at a definedness constraint is being totally ignored here, as it also is in "my Mu:U $a" and other places where it's not currently implemented. Silent ignorance is less than awesome. This should signal an error, until it's implemented. -zefram
