I do not want to drop the BSF dependency completely - in fact this whole issue is about using BSF :-)

I just do not want the Sling API (in the api project) to have a BSF or Java Scripting dependency. I think it is not required in the Sling API to have such a dependency as the ScriptResolver returns a Script and the Script has an eval method.

The implementation of these interfaces will certainly require Java Scripting (BSF 3 that is) for the implementation. But from the point of view of the Sling API, this is an implementation detail.

If SlingBindings would implement the BIndings interface, this would be the only reference to Java Scripting in the Sling API. As I intend to have Java Scripting dependency to be an implementation detail, I think, the SlingBindings, should not use Java Scripting API.
