> * What is your evaluation of the proposal?
The IUO is not a transitional technology, as it is essential to bridge from languages from which Swift evolved, such as C and Objective-C. The proposal doesn't give much consideration to this application of IUOs, and hence, I cannot support the proposal in its current state.
> * Is the problem being addressed significant enough to warrant a change to Swift?
Grant it, the use of IUO outside of bridging is strange and probably a poor practice. However, there seems to exist a requirement and this proposal would make satisfying this requirement more difficult.
> * Does this proposal fit well with the feel and direction of Swift?
> * If you have you 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?
