I assume the “SignedNumber” protocol is the same as the existing one in the standard library. That is to say, Strideable.Stride will now conform to Number and have operators.

Also minor nitpick, would it be too onerous to require Number.Magnitude to be Comparable? Currently it’s only Equatable and ExpressibleByIntegerLiteral.

Sure is

Followed previous discussions, read proposal twice.
