* What is your evaluation of the proposal?This sounds like a great 
move. I recently used the CFNotificationCenter APIs, where I needed an 
UnsafePointer from an Unmanaged and the process was a bit surprising. Good to 
know first off I was even doing it the correct way, and I think this change 
substantially improves it.
        * Is the problem being addressed significant enough to warrant a change 
to Swift?Yes, I imagine the use case of a pointer is the most wanted.
        * Does this proposal fit well with the feel and direction of Swift?Each 
part with Unmanaged and UnsafePointer seem well thought out and logical, and 
this change fits in well.
        * If you have you used other languages or libraries with a similar 
feature, how do you feel that this proposal compares to those?The only language 
I can think of is Objective-C, and I think this matches the flow of __bridge 
and const void * well.
