Topic: Alias enum

nikomatsakis: so maybe we want 3 variants ...
... that unify treats the same ...

Unify doesn't have to change at all then, since it doesn't actually look into the alias (it just puts it in AliasEq, but nothing else)

@nikomatsakis So we talked about these two options:

I'm not sure we came to a conclusion there, but either way, unify treats them the same, and the main implementation work is adding support for impl Trait types, right?

@detrumi sounds right. I think I mildly lean towards the simpler type enum for now
