Well, OK, but the answer also addresses other cases such as function/method decoration, passing arguments to the decorator itself, and passing arbitrary arguments. I agree that it's a little verbose, and the excessive comments and examples do detract from the clarity of the answer a little, but it's an excellent answer, nevertheless, if only because it leaves no use cases unexplored (excepting class decoration, but that's sufficiently orthogonal, I feel).

Your answer isn't wrong, but as an exercise in pedagogy (which is the point of SO, or at least one of its major aims) it leaves a lot to be desired, and wouldn't garner many upvotes. Not everyone understands what the term "syntax sugar" (and really, shouldn't that be 'syntactic sugar'?) means.

>That is all there is to it.

At it's most basic yes, but passing arguments to both the decorator and the decorated function are the real value of the article.

And there are examples, more than I need but they provide different ways of looking at the same thing that different people might find useful.
