Iterator power #

A collection of examples to demonstrate the power of iterators for Go developers who could not create their own iterators to use for/range until Go 1.23 (2024-08-13).

Many of the examples are inspired by Python built-in generators and those from the itertools standard package (which in turn are inspired by functions from Haskell, Standard ML, or APL).
