In pypa/twine#728, I learned that the dict hack for resolving a group of entry points by name is unintuitive, violates static type checks, and still doesn't provide an elegant way to resolve a set of entry points by group and name.

Therefore, I'd like to re-consider the user-interface (API) for entry_points() and its objects. In particular, I want to go back to the drawing board, revisit the requirements, and design something that's simple and elegant in the general case, but also isn't constrained just to the common cases.

This bug represents the motivation for creating #278 and to be more explicit about the motivations and factors driving the change.
