Lookups are designed to represent computations in the context of a pre-existing class.
I guess a Lookup for this use case would have to be based on a pre-existing package, not a class.

Adding disembodied packages (and modules) to the Lookup API would be a reasonable extension.
Likewise, it would be reasonable to extend Lookups to embody the access rights
of one package which is using a qualified export from another package.

We are going a little slow on such extensions because we don't want to add seldom-used complexity.

But we *do* expect to cover, eventually, all the U.dAC use cases, and feedback like this is how we'll get there.
