Specialization would only be one piece of the puzzle, and as you can see, it's not in stable yet.

All of the bits are still too far out to give a good estimate of.

Thanks. Do you expect that to introduce some non backward compatible changes to language (and for example require a new major version)?

Initial work on specialization has already landed on nightly and is backwards compatible. AFAIK, there are no plans to break that.

That's good!

I do not, no, and I would suspect that it'd be a non-starter if it did require it.

Great, thanks!
