Mixin an enum item interferes with ACCEPTS semantics

[grondilu]

The Problem

It seems that when mixing a role to a enum item, &infix:<~~> behave differently.

Expected Behavior

Mixing a role to an enum item should (probably) not interfere with ACCEPTS semantics, at least not for anything not invoking the role. See Steps to reproduce.

Actual Behavior

See steps to reproduce.

Steps to Reproduce

enum coin-flip <heads tail>;
say heads but role {} ~~ heads

Prints False. True was expected.
