[incr Tcl] is the most popular object-orientation language extensions for Tcl. Its object model is comparable to C++, includes multiple inheritance, classes and instances, and property and method visibility modifiers.

It also comes with new [incr Widgets] and [incr Tk] for building complex and custom widgets.
