|
||
|

=head1 DESCRIPTION
|
||
|
|
||
|
This plugin provides a C<.json> vmethod to all value types when loaded. You
|
||
|
can also decode a json string back to a data structure.
|
||
|
|
||
|
It will load the L<JSON> module (you probably want L<JSON::XS> installed for
|
||
|
automatic speed ups).
|
||
|
|
||
|
Any options on the USE line are passed through to the JSON object, much like L<JSON/to_json>.
