=head1 NAME
Data::CleanJSON - Clean data so it is safe to output to JSON
=head1 VERSION
This document describes version 0.002 of Data::CleanJSON (from Perl distribution Data-CleanJSON), released on 2017-01-03.
=head1 SYNOPSIS
use Data::CleanJSON qw(clean_json_in_place clone_and_clean_json);
clean_json_in_place($data);
$cleaned = clone_and_clean_json($data);
=head1 DESCRIPTION
This has the same functionality as L<Data::Clean::JSON> except that the code to
perform the cleaning is pre-generated, so we no longer need L<Data::Clean>>
during runtime.
=head1 FUNCTIONS
None of the functions are exported by default.
=head2 clean_json_in_place($data)
=head2 clone_and_clean_json($data) => $cleaned
