Document alternatives to macro annotations

[jto]

Scala 3 won't support macro annotation, which will break a number of open-source libraries.

AFAIK there is no "official" documented alternative and the only solution currently being tested by the community is to generate code using Scalafix (see simulacrum-scalafix).

The migration guide should offer alternatives to macro annotations.

I think you are right there is no alternative in Dotty for macro annotation.

Thank you for pointing us to simulacrum-scalafix! I will take a closer look at it.

Alternatives can be:

• type class derivation
• dotty compiler plugin (example, doc)
• scalafix
