Here is an interesting way to "distinguish" between L-values and R-values. The following program uses the properties of the conditional operator to implement an IS_LVALUE macro that detects the value-ness of an expression and prints its determination.
I thought of using the conditional operator as I was lying in bed last night. I was going to try it this morning ;-)
