Sets in Modern Go
summary
Concrete claim: Go is adding standard sets and collection conventions for Go 1.28 that turn O(M·N) nested-loop problems into near-linear code using constant-time membership. The work shows a map-backed container/set with one-line methods calling a lower-level mapset API (Collect, InsertAll, ContainsAll, Intersection/IntersectionWith) plus a separate maphash hasher and hashset/hashmap type that accept custom equality and hash (example: case-insensitive hasher using ToLower). The design is in flight but compiles on 1.27 RC.
