Surely I can't be the only one who uses this. I am not looking forward to copying & pasting a reimplementation of the comparison functions into every single project I work on.
This fits into a more general idea of introducing a better “ordering” concept defined in terms of three way comparison results (less/equal/greater). This would then become the primitive that sort would be built on, and would allow deriving the user friendly operators like < and <=.
There was a sketch of this posted to swift-evolution several weeks ago, but I don’t have a link offhand.
