> * What is your evaluation of the proposal?
Given SE-0121 would get accepted, this proposal does only add small additional value, and might even make code unnecessary complicated.
BUT the nil-coalescing operator (??) really should not allow a non-optional on its left hand side.
> * Is the problem being addressed significant enough to warrant a change to Swift?
No, not really once SE-0121 is accepted.
> * Does this proposal fit well with the feel and direction of Swift?
No, too much boilerplate needed in some cases where the coercion is obvious
> * If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?
> * How much effort did you put into your review? A glance, a quick reading, or an in-depth study?
Working with optionals for some while now, and a few minutes thinking through the implications of the proposal.
