Is there a reason why the standard library does not have a protocol like
IntegerArithmeticType but for floating point types?
Improving numerics support in Swift is a part of a long-term plan.
Also, I don't know how many times I've found the need for this:
protocol DefaultInitializable { init() }
Because there isn't a useful algorithm you can write on top of such a
protocol. It is even hard to write a doc comment for it -- what are
the semantics of calling that init? What is the postcondition?
