This thread reminds me to ask if are there any guarantees for ordering
of variant types? Although the implementation indicates that with
type card = Number of int | Jack | Queen | King | Ace
Jack < Queen and Queen < King it also says that Ace < Number 0. I can
see what is going on with the implementation. I'm curious if there
are any ordering guarantees that I can take advantage of? Since the
documentation is silent on this point I doubt it.
Oh, It does seems as if tuples, arrays and lists are always compared
"from left to right". This can be handy when sorting multi-
dimensional data. This seems like a "more natural" ordering than for
variants but, once again, can this ordering be guaranteed for all
ocaml programs?
