SYNOPSIS
Lifts a comparison function to a lexicographic ordering on lists.
DESCRIPTION
An application list_compare comp (L1,L2) uses comp as a basis for comparing the lists L1 and L2 lexicographically, in left-to-right order. The returned value is one of {LESS, EQUAL, GREATER}.
FAILURE
If comp fails when applied to corresponding elements of L1 and L2.
EXAMPLE
- list_compare Int.compare ([1,2,3,4], [1,2,3,4]);
> val it = EQUAL : order

- list_compare Int.compare ([1,2,3,4], [1,2,3,4,5]);
> val it = LESS : order

- list_compare Int.compare ([1,2,3,4], [1,2,3,2]);
> val it = GREATER : order
