Mostly fix compatibility with immutable v0.4.0

List has to be dropped because type aliases are not allowed for generic types.

There's an outstanding issue that Set can't contain pointer values. benbjohnson/immutable#25

I would abandon this package altogether, but there's no Set type in immutable, and its comparer and hasher types are more boilerplate than I want.
