Generics have been around for a while now, and although this has been brought up before, do ya’ll think a built in set data type like golang-set (or something similar) will come to the stdlib? Do you think it should?
I think it would be a great convenience at little to no cost to the practicalities or philosophies of Go.
I find hacking maps to be sets with
map[T]boolormap[T]struct{}to be awkward for the most rudimentary use case, membership checking, and downright onerous for anything more “complicated.”I feel as though the datastructure “an unordered collection of things without duplicates, with constant time lookup” is so simple and useful, I don’t see any reason to keep it out of the language.
