It *did* pay attention to it. If it weren't there, you'd not get such an error,
but instead this one:
C:\consulting\rakudo>perl6-m -e "class A { has $.a; method gist(A:) { $!a } };
A.gist"
Cannot look up attributes in a type object
in method gist at -e:1

No, 'cus it's paying attention to it. Maybe you're expecting the presence of a
:D/:U to imply "multi" on the candidate? This isn't happening (by design,
nowadays). An only method hides any inherited method, multi or otherwise,
because whether the things you inherit from are multi or not is an
implementation detail of the base class.
So, no bug here, I think.
