I don't particularly like the look of function annotations either, but I
don't have a better syntax (aside from swapping the annotation and value).
In this case, I really don't like attribute annotations because it
looks to me like a bunch of line noise without meaning, or some C-like
conditional expression gone wrong.

I didn't like it when Guido posted it on his blog either. I would also
point out that Guido lists attribute annotations as a "maybe". Perhaps
he has become 100% on them, I don't know, but I'm still -1.
In any case, you still haven't provided any use-cases, or an example
where developers have been asking for the feature and could show that
*not* having the feature was constraining them in some significant way.
