Hi Stephen,

You write

>   * FloatingPoint should conform to Equatable, and Comparable

but the documentation for Equatable and Comparable states that == and < 
must implement an equivalence relation and a strict total order, which 
is incompatible with the default IEEE-754 implementation of these 
operators when NaN values are involved. How do you resolve this conflict?
