@anatoliykmetyuk, after this PR is merged, could you fill in this list with all the latest progress you did in the community build?

@anatoliykmetyuk @liufengyun do we have a simple project that uses this scheme in the community-build?
I know about scalatest but its build is to complex.

@nicolasstucki I have a tiny project with a single macro call for evaluation of constants. Here is my currently failed attempt to add Scala 3 support for it: https://github.com/plokhotnyuk/expression-evaluator/pull/40/files
Also, a good small candidate would be the macrolizer library. cc/ @sirthias

Macro is one of the big change in Scala 3. Those preliminary guidelines are much valuable to push the migration forward.
Looking forward to the list of macro projects in the community build.
