I agree with Andrew. It takes me no extra time to understand, and I
find it *very* natural. If anything, I find it *faster* to understand
than your if construct above.

You and some others may agree that you shouldn't use it. Fine. But
that doesn't make it bad. There are a lot of other programmers who find
it quite easy and natural.
