qb: Array producing functions don't work?

[msullivan]

        q = default.GameSession.select(
            "*",
            players=True,
        ).filter(
            lambda g: std.array_agg(g.players.id)
            == std.array_agg(green.users.id)
        )

fails at runtime with

  File "/home/sully/src/e/edgedb-python/gel/_internal/_qb/_generics.py", line 300, in wrapper

AttributeError: type object 'Array[models.orm.__shapes__.std.uuid]' has no attribute '__gel_type_class__'

And it fails to typecheck because __eq__ is not overloaded on Array in a way visible to the typechecker. (And the way not visible seems broken?)
