Put this code through Rakudo​:

use v6;

role TestRole {
  method foo() { ... }
}

class TestClass does TestRole {
  method foo() { say "render"; }
}

my TestClass $t .= new();

Rakudo complains that the role composition causes a method conflict
because of 'foo', but TestClass​::foo should be overriding TestRole​::foo.
jnthn speculates on IRC that it's a result of some refactoring in rvar,
where some code got removed and not put back.

19​:57 * jnthn suspects that (a) some code was pulled out in rvar and
not re-instanted and (b) we didn't have a test for this so it went
unnoticed.
19​:57 <@​jnthn> rvar removed a bunch of stuff to make refactoring easier
and then added it back in.
19​:57 <@​jnthn> I think I know exactly what we've lost.

matt-w also added that as a test case to t/spec/S12-roles/composition.t.

Fixed in r35443, and moritz++ unfudged the test.

Thanks!
