J.D. Smith (jdsmith@astrosun.tn.cornell.edu) enlightens us
us with yet another interesting idea of how pointers can
be used. (But this time he uses a whimsical style, which
I haven't seen from J.D. in a while Oh, wait, it's Friday
night. He must of just gotten back from the weekly Astronomy
bash. :-)

In any case, I like his articles very much because I always
learn something from him. But I am confused by this first
statement:

> I would expand this step to include storing a copy of the pointer
> elsewhere, to eliminate the problem of dissappearing uvalues so common
> in non-blocking widget applications.

What disappearing uvalues!? I've never heard of this before,
and I like to think of myself as a worldly sort of guy. :-(

If the head is not too bad this morning, J.D., can you
elaborate a bit on what this is about? Many thanks.

Cheers,

David

P.S. I just tried that transmogrifying trick J.D. recommended.
It *is* karmic! :-)
