Re: [swift-evolution] [Review] SE-0016 - Adding initializers to Int and UInt to convert from UnsafePointer and UnsafeMutablePointer

One of the alternatives discussed in the proposal was adding mathematical operators to UnsafePointer so you can manipulate the pointers directly, such as XORing them, checking alignment, etc. I would very much prefer that we add operators and functions to UnsafePointer to express intent.

Re: [swift-evolution] [Review] SE-0016 - Adding initializers to Int and UInt to convert from UnsafePointer and UnsafeMutablePointer

Thinking through this proposal, I really favor the operator approach rather than adding these conversions so my vote is -1. (If you really know what you're doing you can already do an unsafeBitCast so this isn't a problem I've had in the real world) >Because some of these operations are

Re: [swift-evolution] [Review] SE-0016 - Adding initializers to Int and UInt to convert from UnsafePointer and UnsafeMutablePointer

Just for note, an alternative that works right now (whether intentional or not) is this: let rawAddress: Int = UnsafeMutablePointer(nil).distanceTo(myPointer) This gives the distance in bytes (so on 95% of all platforms, the raw address). It currently isn't clear that this is how you can
