If you saw code like this:

	if (x > y)
	    z = x;
	else
	    z = y;

would you think it's a bit silly?

IMHE 'never' means about 50% of the time you will find something you
hadn't thought of.

It's not less readable *to me*.  Admittedly, i've done this sort of
thing a lot.  For a newbie it might make him woozy.

There's a place for statement macros.  When it's next to impossible to
make an expression macro, or it's so horribly unreadable that it makes
*me* woozy, i don't have a problem with it.
