>       • What is your evaluation of the proposal?

I am enthusiastically in favor for @noescape. I am also in favor for 
@autoclosure.

However, I think there is a larger issue here. In several recent attribute 
discussions—particularly around @autounwrapped and @discardable—options have 
been discarded at least partially because the attributes didn't make sense as 
decorations on a property or return value's type, and yet there was no way to 
decorate the value itself.

@noescape and @autoclosure *do* make sense as attributes decorating a type, and 
they should be changed to do that. But make no mistake: the concept of 
attributes on parameters and return values *is* still needed, because already 
today it is preventing us from adopting excellent designs.

Yes. Unutterable types are a big problem.

>       • Does this proposal fit well with the feel and direction of Swift?

Yes.

>       • If you have used other languages or libraries with a similar feature, 
> how do you feel that this proposal compares to those?

I don't think I have relevant experience.

Read the proposal and participated in discussion.
