URI-1.22

[Gisle Aas]

URI-1.22 is now propegating on CPAN.  New since last release is sip:
and sips: support contributed by Ryan Kereliuk and a URI::QueryParam
module that does this:

NAME
    URI::QueryParam - Additional query methods for URIs

SYNOPSIS
      use URI;
      use URI::QueryParam;

      $u = URI->new("", "http");
      $u->query_param(foo => 1, 2, 3);
      print $u->query;    # prints foo=1&foo=2&foo=3

      for my $key ($u->query_param) {
          print "$key: ", join(", ", $u->query_param($key)), "\n";
      }

DESCRIPTION
    Loading the "URI::QueryParam" module will add some extra methods to URIs
    that support query methods. These methods provide an alternative
    interface to the $u->query_form data.

    The provided query_param_* methods on pupose made identical to the
    interface of the corresponding "CGI.pm" methods.

    The following additional methods are made available:

    @keys = $u->query_param
    @values = $u->query_param( $key )
    $first_value = $u->query_param( $key )
    $u->query_param( $key, $value,... )
        If $u->query_param is called with no argments it returns all the
        distinct parameter keys of the URI. In scalar context it returns the
        number of distinct keys.

        When a $key argument is given it returns the parameter values with
        the given key. In scalar context only the first parameter value is
        returned.

        If additional arguments are given they are used to update successive
        parameters with the given key. If any of the values provided are
        array references then the array is dereferenced to get the actual
        values.

    $u->query_param_append($key, $value,...)
        The $u->query_param_append method adds new parameters with the given
        key without touching any old parameters with the same key. It can be
        explained as a more efficient version of:

           $u->query_param($key,
                           $u->query_param($key),
                           $value,...);

        One difference is that this expression would return the old values
        of $key, while the query_param_append() method will not.

    @values = $u->query_param_delete($key)
    $first_value = $u->query_param_delete($key)
        This method will delete all key/value pairs with the given key. The
        old values are returned. In scalar context only the first value is
        returned.

        Using the query_param_delete() method is slightly more efficient
        than the equivalent:

           $u->query_param($key, []);

    $hashref = $u->query_form_hash
    $u->query_form_hash( \%new_form )
        This method will return a reference to a hash that represents the
        query form's key/value pairs. If a key occurs multiple times, then
        the hash value will become an array reference.

        Note that sequence information is lost. It means that:

           $u->query_form_hash($u->query_form_hash)

        is not necessarily a no-op as it might reorder the key/value pairs.
        The values returned by the query_param() method should stay the same
        though.
