Toolkit is broken on Native

[Arman Bilge]

This is due to VirtusLab/scala-cli#2426.

//> using toolkit latest
//> using platform native

@main def main = println("hello world")

Thanks for the reporting, I think we could even include test for that in the CI

I'm not able to reproduce the problem on MacOS with Scala-CLI 1.1.2:

% scala-cli S.scala
[warn] ./S.scala:1:11
[warn] Using 'latest' for toolkit is deprecated, use 'default' to get more stable behaviour

hello world

Yes, this will no longer be reproducible because scala-cli has released several new versions that upgrade the Scala Native toolchain and meanwhile toolkit has not released anything new. But it could happen again unless there is a plan so it won't happen again. In the Typelevel Toolkit we build a small app against the latest scala-cli just to verify everything still works before merging any PRs to update libraries.

Anyway, I will close as stale.

@armanbilge it's a good idea to add a small example toolkit app build to CI, I'll try to do this, meanwhile we're waiting for sttp to get on sn 0.5
