That said, it's not true that static_cast only causes reinterpretation as the desired type: it can also invoke a conversion operator, which can then return absolutely anything. static_cast only ensures that the compiler can find a previously defined route to perform the conversion, be it a relation by basic type class or inheritance, a conversion operator, or probably various other things I can't think of right now. In fact, due to it being satisfied by an inheritance relationship, you can e.g. cast a Gtk::Widget* that really points at a Gtk::Label to a Gtk::Frame, and it won't complain, because it assumes you typed a sensible thing: it only checks the definedness of the conversion, not the potential danger level.
