Expected features in Scala 2.14?

Assuming the SIP process will manage to catch up with all the new Scala 3 (dotty) features, which features are expected to appear in Scala 2.14? It is completely understandable that all the new metaprogramming-related features are out. I think that if the leap between 2.14 and 3 is too large it can deter the community from migrating, so the more features implemented in 2.14, the better.

The features I’m hoping for:


I’m pretty sure I’ve seen all of those mentioned in the context of Scala 2 except implicit function types. Multiple implicit parameters might have been a long time ago though.
