What goes into a review?
The goal of the review process is to improve the proposal under review
through constructive criticism and contribute to the direction of Swift.
When writing your review, here are some questions you might want to answer
in your review:
* What is your evaluation of the proposal?
I've used classes that were marked final that I wish were not.
I've never used a class that was not final that I wish was marked so.
* Is the problem being addressed significant enough to warrant a
change to Swift?
I don't think the 'problem' described is a problem.
If you expose a class, you should think about how it might be subclassed.
In the very rare (and still too frequent) case when something should not be
subclassed, you should document it that way and explain why.
* Does this proposal fit well with the feel and direction of Swift?
I hope not.
