The reality is that we are going to have to look at each instance of
S?List in the API and determine whether we can treat it as an opaque
type or whether we have to create a custom IList implementor to marshal
its elements. Don't get your undies in a bunch over SList.cs. It was a 2
minute hack to get around a build problem early on.

Dude, please.  Would all the folks who have actually used Gtk# and feel
it was a huge pain to adapt to the paradigm shift please step forward?

Widget*?  The GObject pointers are only used to invoke native methods. 
The native methods have all manner of cast/type checking built in. It's
not like Gtk# is using the handles to indescriminately "scribble" across
the heap. If we want to be completely anal-retentive, we can always add
a little glue check to call G_IS_OBJECT in the base GLib.Object(IntPtr)

Impressively melodramatic.
