I do think we need programmatic control over bindings. I think that
was one of my first questions when we implemented the @Injected
databinder. I agree with you that the current state is a bit too
"magical," and I think that the suggestions you've brough up will help
to eliminate that.
+1 to individual @Bind and also aggregate @Autobind / @Autobound annotation
