Also, add Dialect.allowParamClauseInterleaving. Based on #2820.

Looks great! I will take a look a bit later this week, but are we ok releasing a new version before this gets merged just in case? 4.7.0 most likely, no?

if this is likely to be released, but we want to do it in next release, then i'd still like to add an intermediate change in this release. i will send it shortly.

I believe this implements faithfully what is in the SIP
(given both the implementation and the tests)

Really nice work, thank you !

[tgodzik]

I think we should only merge this one after scala/scala3#14019 is finalized.

[Sporarum]

scala/scala3#14019 has been merged !

But it will of course not be usable until the next release of Scala

[tgodzik]

lampepfl/dotty#14019 has been merged !

But it will of course not be usable until the next release of Scala

It should be experimental in 3.3.x, right? We can merge it anyway in Scala313 dialect I think, should safe.

meaning, instead of Scala3Future, add the flag to another dialect?

Yeah, I would make it into the default Scala3 dialect, unless it could cause issues?

So instead of replying I edited your answer 😵‍💫 Sorry about that! :|

Done. Added to 3.3 (which is what scala3 points to), along with fewer braces.
