Golf'd to​:

role A { method m {} }
role B does A {}
class C does A does B {}

Method 'm' must be resolved by class C because it exists in multiple roles
(A, B)

Note that the same issue leads also to​:

role A { has $a }
role B does A {}
class C does A does B {}

Attribute '$!a' conflicts in role composition

A number of devs discussed this on #perl6 with the useful part starting
here​:

and ending with jnthn's thoughts.
