No, that's not really possible. The stdlib is packaged with the Go compiler and is very interdependent. It also wouldn't help you a lot, because in go1.15, the `io/fs` package has no implementation yet. For example, (*os.File).Stat does not return the correct type, compare https://tip.golang.org/pkg/os/#FileInfo with https://golang.org/pkg/os/#FileInfo
If you want to experiment, you have to use a go version compiled from tip. You can already develop against it, if you use build tags to guard on go1.16 (though keep in mind that the interfaces could, theoretically, still change). Otherwise you just have to wait for go1.16. A beta should be released soon (probably next week, AIUI). On Thu, Dec 3, 2020 at 12:32 AM Matt Mueller <mattmue...@gmail.com> wrote: > Hey there, I'd like to try the io/fs package on Go 1.15.
