(optional)

So that the same module can be used several times in a class.

I don't really see the benefit. Making module usages named just to allow multiple inclusions in the same class sounds like a theoretical edge case with almost no real world value. Modules are about code sharing, not about holding instance data.
Using a module multiple time inside a class hierarchy seems more like a real world use case, and since this works now (#846) and does not require naming, I will close this issue.
