By viktorklang:

The user shouldn't pollute everything with context everywhere. "self" is on Actor, and if you don't use any of the context-things there's no additional typing, and if you want to have the full scope, you simply do: import context._
In this way we do not pollute the namespace on Actor by default, we can add new methods to Context without accidentally breaking peoples Actors etc.
