this means, the @type constraint would be inherited, but the member template would not?

this gets closer to the question.
does this mean “duck type” constraints are not inherited as the member template is not inherited, but an @type would be inherited, as the generated frame "inherits any `@` flags”?
this is the behavior which i believe i had not seen in the tests.
i may have misconstrued the results.
in any case, if that is the intent, it is a clear implementation requirement.
