	Somebody mentioned economy of expression being a good thing;
agreed.  In this particular case the idiom is so well ingrained that I
don't think twice about it.  In fact, doing it any other way would
require more thought.

	Saving a line or two of source makes it that much more likely
that the entire 'phrase' will fit on your screen at one time, enhancing
comprehension.  About the only time I would split the assignment and the
test is when the line would run off the edge of the screen otherwise.
