However I found "get_widget<Type>()" syntax concise and typesafe, and
simplifies code so that one won't need to set up a NULL pointer
beforehand.  Recently there is a discussion on gtk-devel-list that
discussing the same issue in C getter/setter API, and some people do
feel a getter returning void not satisfying.

Just my two cents :)
