Good idea. I will try it. I also figured out a way to architecture my
program differently to avoid this problem. But this idiom might be
handy in certain situations. Suppose you need to provide a callback
function with a fixed signature to some library routine. But you want
to add extra contextual data to your callback. This just might be the
ticket.
