Sorry, but that doesn't fly.  That's a clearly separate function
that should have a simple, single call somewhere in the application.

The AOP logging example is talking about a "cross-cutting concern"
(did I get that right?) where one wants to log *all method calls*
in an object.  It's a developer tool, not something that you would
use for call logging.

And even if it were, I'm still looking for real-world examples, not
hypothetical ones.
