Description

Currently, Sling Models only supports dependency injection for fields (or interface getter methods), but not for constructor arguments. This ticket is for discussing what this constructor dependency injection should support, and perhaps finally provide a patch to implement it.

This is somewhat related to SLING-3715 for class-based dependency injection, because this would come in especially handy for constructor injection.
