Advancing the container/set design?

[Frederik Zipp]

Some time ago, Ian started a discussion about a potential proposal for a container/set package: https://github.com/golang/go/discussions/47331

The main point of uncertainty was iterating over elements. Now that iteration is solved in Go 1.23, is it perhaps time to advance this design and turn it into a proposal for the 1.24 release cycle?

+1 on this.

At the moment, every module that needs a set implementation ends up creating its own, either using map[T]struct{} or map[T]bool. Having a set implementation in the standard library would significantly increase operability between modules, even if the implementation is trivial.
