With Rakudo 153a4a8 on Parrot r36239, I get the following​:

$ perl6 -e 'role A {}; class B { has A $!a }; B.new'
Type mismatch in assignment.
[...]

I see nothing wrong with the above, so I don't think the error is justified.

Aye, there were a range of quirks/issues in role type checking, which
I've now fixed in git 88b6c25. Plus added some tests for roles being
used as type constraints.

Thanks,
