-// This module adds high-level functions and related constructs:
-// - "scan" family of functions
-
-// Notes:
-// - missing high-level functions are provided with the compatible API:
-// scanl, scanl1, scanr, scanr1
-
-// Defined methods:
-// - take any valid lambda argument as the functional argument
-// - operate on dense arrays
-// - take a string as the array argument
-// - take an iterator objects as the array argument (only scanl, and scanl1)
