On the first, we went around a few times, and I think I’m convinced we don’t need to do anything special here, at least until we get to pattern matching in switch. Nesting is fine; static import helps; we can consider a similar thing for type patterns of sealed types as we do for enums, where we allow the outer class to be omitted when switching over a sealed type with inner subtypes.
An extractor is the implementation of a pattern. We don’t yet have hard terminology for this, so this can be rewritten to “support for deconstruction patterns” until then.
