Comment(by rlm):
Franco,
Thanks for the incredibly detailed explanation! The main reason I was
asking is that there is no indication why this is okay in the code itself.
Could you put a sentence or two, maybe just in a comment, explaining why
this is done? Maybe something like "When the user asks for `a<b`, rich
comparison is used, and this is implemented only to enable sorting." Also,
if the result of sorting isn't consistent (e.g. cmp(a,b) == cmp(b,a)),
this should be mentioned too, I think.
