// This module adds high-level functions and related constructs:
// - reversed versions of array-processing functions similar to standard JS functions
// Notes:
// - this module provides reversed versions of standard array-processing functions:
// forEachRev, mapRev, filterRev
// Defined methods:
// - take any valid lambda argument as the functional argument
// - operate on dense arrays
// - take a string as the array argument
