We had kind of an inverse discussion a while ago when someone asked
about the fate of aspect oriented programming (AOP) in Python. My
answer was that technically "aspect weaving" using code generators is
dead in application programming [1] and decorators are handy,
lightweight, local and controllable while serving very similar
purposes.

[1] There are occasions where source code weaving might still has its
place. Profiling for example or code coverage. Just examine this
interesting blog article:

and the subsequent discussion.
