Must casting destroy lvalueness?

[John Gilmore]

One interesting thing for people who don't understand this issue to do is
to ask yourself what the compiler should do for a construct like:

	int i = 17;
	((double)i)++;

Again, don't post your favorite answer to the net.  Just think about it.

PS:  When you're done that one, try:

	double i = 17;
	((int)i)++;
