Also think this is a good call. Though the second comment has merit too, I think it would be good to have some common abstraction right away, like we had io.Wr

Also think this is a good call. Though the second comment has merit too, I think it would be good to have some common abstraction right away, like we had io.Writer, io.Reader, etc. so everybody doesn't define their own, as it'll take time to crawl out of that. Although in practice it did work out well with error wrapping which was first in libraries and then the stdlib defined an interface for them, which resulted in all libraries adopting that. > Similarly, if constraints isn’t part of 1.18, there will be a lot of independent redefinitions of orderable types. I don’t think we’re going to learn from experience much that could change that package now.
