### Introduction

This library is still in it's infancy and only supports very few types
of noise yet.

It offers both heavily optimized (tested only on SBCL so far) and
reference implementations if they are available.


### To Do

From Matrix #lispgamedev:matrix.org:

> If anything, just grep for safety 0 and remove that ASAP :)

> Or at least do it in a (locally (declare ..)) sparingly like around array accesses where you are sure your indices are correct.
