---------------------------------------
Hi [~NickBurkard] ,
Nice work!
I've already migrated a big codebase from 2.12 and 2.13, and regarding your
point #6 (Seq changing from mutable to immutable) I think the best is to stick
with mutable by importing {{scala.collection.Seq}} everywhere it's used.
It's tempting to switch to immutable as it's preferred in Scala, but that
sticking with a mutable Seq is a good way to migrate to 2.13 more easily (and
optionally switch to immutable Seq later on). Scala 2.13 is already complex
enough because of the massive changes in the collection API to avoid adding
more.
