Array::Sparse - role for sparsely populated Arrays

SYNOPSIS
========

    use Array::Sparse;

    my @a is Array::Sparse;

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

Exports an `Array::Sparse` role that can be used to indicate the implementation of an array (aka Positional) that will not allocate anything for indexes that are not used. It also allows indexes to be used that exceed the native integer size.

Unless memory is of the most importance, if you populate more than 5% of the indexes, you will be better of just using a normal array.

Since `Array::Sparse` is a role, you can also use it as a base for creating your own custom implementations of arrays.

Iterating Methods
=================

Methods that iterate over the sparse array, will only report elements that actually exist. This affects methods such as `.keys`, `.values`, `.pairs`, `.kv`, `.iterator`, `.head`, `.tail`, etc.
