The day that one guy leaves the team, suddenly you have code that's become
a bit tricky to maintain. Our philosophy is that everyone should be able to
contribute anywhere although I agree with you: there is such thing as using
a decorator as a black box, and even diving into it isn't that hard. Notice
I didn't say we don't use these features at all, we just tend to avoid them
when a more familiar approach exist. Even so, maybe we are wrong to do so,
and the code would be clearer if we used more features. Maybe we just lack
the expertise and we are indeed stuck in an old mindset, after all. Anyway,
I have some directives to make my code easy to access and must compose with
what I would call industrial constraints.

As a gambler I can't refuse that bet proposal, no sir :) Expect me to come
back with a piece of code and/or questions about CPython engine.
