This is a collection of Go packages for testing additions and changes to standard library packages as well as some popular x/ packages to make use of type parameters (generics).
This is a testbed for experimentation. I intend to follow the normal semantic versioning rules but there may be a lot of churn. As these sorts of packages are accepted into the standard library or x/ repos, I intend to deprecate and freeze my versions. For any which prove useful but which seem unlikely to be headed for acceptance into the Go repos, I may move them to more permanent locations.
Generics are a nice language feature with some more-or-less obvious candidate uses within the standard library. The Go team is rightly being very cautious and methodical about introducing these changes. But I'm impatient! I want to use them now.
For example, golang/go#45955 describes a proposal for a new slices package.
This was later made available for use as
golang.org/x/exp/slices
to let folks use the proposed API while it was still under discussion.
Similarly, golang/go#47331 is a discussion about a new container/set package.
But, as of October 2022, no container/set package has been provided in
x/exp. So that's where this repo comes in.
