# Lazy Generators

module
  x-oz://system/Generator.ozf

This module provides lazy generators, i.e. functions that return lists which are lazily computed concurrently, by-need

## Exports

`{Generator.Tails +L ?Tails}`
  returns a lazy list of all non-empty tails of list `L`
`{Generator.count +From +To +By ?L}`
  returns a lazy list of integers starting at `From`, ending at at most `To`, and in steps of `By`. Whether we count up or down is determined by the sign of `By`
