Aka using a library

[antonvs]

That's more typical of a framework than a library. This is one of the areas where the difference becomes clear: with a library, you will see your own methods in the call stack somewhere, and be able to tell what got called and why; with a framework, it's often not so simple.

Regardless, this isn't an annotations phenomenon.
