    Version 1.49.90
    
    - New API: GObject.registerClass(), intended for use with ES6 classes. When
      defining a GObject class using ES6 syntax, you must call
      GObject.registerClass() on the class object, with an optional metadata
      object as the first argument. (The metadata object works exactly like the
      meta properties from Lang.Class, except that Name and Extends are not
      present.)
    
      Old:
    
          var MyClass = new Lang.Class({
              Name: 'MyClass',
              Extends: GObject.Object,
              Signals: { 'event': {} },
              _init(props={}) {
                  this._private = [];
                  this.parent(props);
              },
          });
    
      New:
    
          var MyClass = GObject.registerClass({
              Signals: { 'event': {} },
          }, class MyClass extends GObject.Object {
              _init(props={}) {
                  this._private = [];
                  super._init(props);
              }
          });
    
      It is forward compatible with the following syntax requiring decorators and
      class fields, which are not in the JS standard yet:
    
          @GObject.registerClass
          class MyClass extends GObject.Object {
              static [GObject.signals] = { 'event': {} }
              _init(props={}) {
                  this._private = [];
                  super._init(props);
              }
          }
    
      One limitation is that GObject ES6 classes can't have constructor()
      methods, they must do any setup in an _init() method. This may be able to be
      fixed in the future.
