Scalafix is not able to parse Scala 3 nightly version

[WojciechMazur]

scalafix fails to parse nightly version of Scala3 which differs from nightly version of Scala 3
Example of version 3.6.0-RC1-bin-20241008-3408ed7-NIGHTLY

Issue found by Scala 3 Open Community Build in 3 projects using automatic application of scalafix on compile:

• gemini-hlsw/lucuma-schemas - Open CB logs
• tkrs/orcus - Open CB logs
• xuwei-k/unused-proto - Open CB logs

Thanks for the report. We need a quickfix like #2109. I'll have some time this week end hopefully.

Hello, any news on that front? Scala 3.6.2 is out and 0.13.0 can't parse it either e.g. it fails on new multiple bounds syntax (the have to be enclosed with {}) with:

[error] .../Foo.scala:151:34: error: illegal start of declaration
[error]   private def bar[F[_]: { MonadThrow, Concurrent }](
[error]                                  ^^^^^^^^^^

It's not related to this issue, you might be intrested in scalameta/scalameta#4068 that introduced new givens syntax to scalameta parser used by scalafix.

This issue was about not being able to version strings used by Scala 3 nightlies, not the Scala 3 syntax

I created a new issue for parsing scala 3.6.2 given syntax, feel free to post your example here as well: #2138
