It might be useful to add to the language a combined function such as (argminmax proc lst) that returned both the minimum and maximum values of applying proc to lst. So that for very large lists (or for very large numbers of lists where you need to know the min and max values in the lists) instead of having to traverse the lists twice (once with argmin and once with argmax) you'd now only have to trarverse the list once with argminmax.
