Answer 1

Dependency Injection itself can be done without any tool, framework or container support. You only need to remove news from your code and move them to constructors. The one tedious part that remains is wiring the objects at "the end of the world", where containers help a lot.

Though with Scala's 2.10 macros, you can generate the wiring code at compile-time and have auto-wiring and type-safety.
