It is.

So far both delegate for and given as are available. We are experimenting with what works best. That’s not a breaking or conceptually new change, hence we did not include it in the article.

Not publishing there is something to experiment with seems to defeat the purpose of said experimentation.

7

did we change delegate to given? :expressionless:

Yes. Still no final verdict on the matter. See https://github.com/lampepfl/dotty/pull/6773
