I think that a possible option would be making GLib.SList and GLib.List
implement all those useful interfaces: ICollection, IList,
IEnumerable... And then provide constructors for all of them (the 2
types and the interfaces).

May be it would be nice to add a RadioButton (params Gtk.Button []
buttons) constructor too (and then create the GLib.SList that is passed
to unmanaged code from the array).
