> What is your evaluation of the proposal?
+1, this is a fantastic proposal! I
The proposal does not specifically call out whether a class may inherit from a
subclass of a superclass constraint when a typealias is used in the inheritance
list. I believe the following should be valid, but it would be a good idea to
make that explicit:
class B {}
class D: B {}
protocol P {}
typealias BP = B & P
class Foo: D, BP
> Is the problem being addressed significant enough to warrant a change to

Yes, we are not able to correctly import class constrained protocols from
Objective-C.
> Does this proposal fit well with the feel and direction of Swift?
Very much.
> If you have used other languages or libraries with a similar feature, how do
> you feel that this proposal compares to those?
N/A
> How much effort did you put into your review? A glance, a quick reading, or
> an in-depth study?
In-depth study of the original drafts. Quick read of the final review proposal.
