A small package containing a collection of reduce functions for roc data structures. Reduce behaves like walk, but doesn't require an accumulator argument, instead simply using the first element in the structure as the accumulator.

Functions are available for: List, Dict, and Set, and include left and right variants for lists, and key, value, and (key, value) versions for Dict.

Two names are provided for each function. A function named for qualified use, and a function named for unqualified use. For example:

import red.Reduce exposing [reduce_list_left]

a = Reduce.list_left([1, 2, 3], Num.add)
b = reduce_list_left([1, 2, 3], Num.add)
