Golang proposal: container/: generic collection types

Well, better late than never. Stuff like sets or a typed heap is long overdue. Maybe they'll even add iterator API for database/sql results this decade too (something like my pull request for sqlx https://github.com/jmoiron/sqlx/pull/990 but maybe more polished)

On one hand I'm glad to see this being added, but its becoming obvious building generics into the language as-is just isn't a good fit. Hopefully Go v2 can solve this at a more foundational level while still allowing interop or easy porting form current go code.
