That syntax simply hadn't been implemented yet.
PR https://github.com/rakudo/rakudo/pull/1178 submitted to implement it.
Note that a side-effect of that PR is that even when you are not in a class,
you have to use e.g. ($).^mro if you want to introspect an in-place
anonymous variable... which is probably not something many people would
ever want to do, so not a big deal.
