  to_json
       $json_text = to_json($perl_scalar)

    Converts the given Perl data structure to a json string.

    This function call is functionally identical to:

       $json_text = JSON->new->encode($perl_scalar)

  from_json
       $perl_scalar = from_json($json_text)

    The opposite of "to_json": expects a json string and tries to parse it,
    returning the resulting reference.

    This function call is functionally identical to:

        $perl_scalar = JSON->decode($json_text)
