val (<>) : bat__compare_t -> bat__compare_t -> bool
val (>=) : bat__compare_t -> bat__compare_t -> bool
val (<=) : bat__compare_t -> bat__compare_t -> bool
val (>) : bat__compare_t -> bat__compare_t -> bool
val (<) : bat__compare_t -> bat__compare_t -> bool
val (=) : bat__compare_t -> bat__compare_t -> bool
