I'm gonna take vote hits, but truth is needed here. Python Decorators and C#/Java "attributes" are a sham. If their OOP model were powerful enough, they could just use OOP composition to get the same thing and not have to invent a new kind of thing: it would all just be objects referencing objects. They are a sign of poor or obsolete language design.

True, it's hard to just throw everything out and start over, but at least recognize the problem so that next generation of languages can solve/avoid it.

Removing or softening the distinction between object and class is perhaps a start.

Aren't decorators just syntactic sugar for composition?

In a way. However, I'd probably choose a different syntactical shortcut that looks more like the existing syntax or is a variation of.
