What is your evaluation of the proposal?
+1. I feel like this is a logical step forward for escaped identifiers.
Is the problem being addressed significant enough to warrant a change to Swift?
Yes, as I stated on the discussion thread, there are certain classes of APIs which will benefit from being able to use more expressive identifiers:
Does this proposal fit well with the feel and direction of Swift?
Given that escaped identifiers already exist, this already feels like natural Swift to me. I believe it fits well.
If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?
I can't think of any examples at the moment.
How much effort did you put into your review? A glance, a quick reading, or an in-depth study?
I followed along and contributed to the original discussion.
