    + Add support for defaults, and our own, very, _very_
      simplicistic "expression parser" (which blindly splits on comma.
      This means that the following is now supported:
        sub foo( $bar, $baz='default' ) {
          return $baz
        };
        print foo("two","parameters"); # parameters
        print foo("one");              # default

      The following will still fail horribly, because we don't parse expressions:
        sub foo( $bar, $baz=bar(1,2) ) {
          print $baz # "default"
        };

    + Add our own fake 'experimental::signatures' warning category
      if we install our filter so that "no warnings 'experimental::signatures'"
      doesn't raise an error on Perl versions where we install our filter

    + Check does now not use the version of Perl but checks
      `use feature 'signatures'`
    + You can force the use of the module using an environment variable
      (not that you should)
