/**
 * Takes a list of predicates and returns a predicate that returns true for a given list of
 * arguments if one or more of the provided predicates is not satisfied by those arguments. It is
 * the complement of Ramda's allPass.
 *
 * The function returned is a curried function whose arity matches that of the
 * highest-arity predicate.
