Thanks to this question I put on Gitter, and the subsequent answer, TIL about how packages/packaging works in Scala 2 with package objects and toplevel definitions in Scala 3.

toplevel definitions

Scala: Accessing a protected field when inheriting from a class in a different package
An example sbt build.sbt file for a Scala 3 (3.0.0-M3) project (including scalacOptions)
Scala 3: Multiple packages in one file (syntax, examples)
Scala 3: Package objeccts are deprecated, how to create types in a top-level package and use them everywhere in your project
Implicit methods/functions in Scala 2 and 3 (Dotty extension methods)
