NAME
====

Array::Sparse - class for sparsely populated Arrays

SYNOPSIS
========

    use Array::Sparse;

    my @a is Array::Sparse;

DESCRIPTION
===========

This module adds a `is sparse` trait to `Arrays`. Its only use is to provide a more memory-efficient storage for arrays that are **very** big (as in millions of potential elements) but with only a very limited of elements actually given a value (maximum about 5 %). Unless memory is of the most importance, if you populate more than 5% of the keys, you will be better of just using a normal array.
