I've also observed that the issue affects.module and.attr and.load. I'm trying to decide what's the best behavior here. I think it should fail early, at construction time, but right now, the interface is open to mutation of the entry point properties. Probably those should be madefinal.

Additionally,EntryPoint could probably subclassSimpleNamespace except thatEntryPoint currently allows for positional arguments. Let's deprecate that behavior and require keyword arguments.
