I touched UniqueArray - looks very good. Though I am missing something like consuming/borrowing func map(...) function family.

This will at least require [Pitch] Borrowing Sequence for the borrowing variant. But I also think there are still a lot of open questions:

• how do we differentiate between borrowing/consuming and variants that only consume the elements but not the collection.
• what will the result type be? There are now multiple Array like types.
• Should there also be lazy variations or should it be lazy by default?

and probably more.

Also wonder if some preview of Dictionary is available for non-copyable types?

Not a preview but a draft is up: Ownership-aware Set and Dictionary variants by lorentey · Pull Request #573 · apple/swift-collections · GitHub
