Correction, kindly pointed out by an RSI developer... the feature
introduced to put a halt to David's perverse misuse of base widgets was
*handles*, not pointers. Interestingly, he also filled me in that
handles in fact *were* base widgets internally, stripped of everything
by the uvalue. I had obviously attempted to elide those from my memory,
and not without due cause. Let's hope we remember handles only as a
curious side-excursion in IDL history, and insist on pointers in all our
code.
