=head1 NAME

Array::Iterator::Reusable - A subclass of Array::Iterator to allow reuse of iterators

=head1 VERSION

This document describes version 0.12 of Array::Iterator::Reusable (from Perl distribution Array-Iterator), released on 2017-07-04.

=head1 SYNOPSIS

  use Array::Iterator::Reusable;

  # create an iterator with an array
  my $i = Array::Iterator::Reusable->new(1 .. 100);

  # do something with the iterator
  my @accumulation;
  push @accumulation => { item => $iterator->next() } while $iterator->has_next();

  # now reset the iterator so we can do it again
  $iterator->reset();

=head1 DESCRIPTION

Sometimes you don't want to have to throw out your iterator each time you have exhausted it. This class adds the C<reset> method to allow reuse of an iterator. This is a very simple addition to the Array::Iterator class of a single method.
