Well thanks for that ;-)

I don’t think it would conflict in this case, since I don’t think there’d be a reason to mix Enum item access with Type item access. Especially because the Enum itself might be used in the type signature (though not item access on the Enum, I’d think).

I think it’s enough of an edge-case that I still like the parallel it provides, but I appreciate the reality check.
