To say nothing of the comma operator or the switch statement.  :-)

However C follows the "one, two, many" approach to terms.  You can
say:

	OP TERM				--x *x -x &x etc
	TERM OP				x++ x-- etc?
	TERM OP TERM			x+y x-y x*y etc
	TERM [OP TERM]...		f(x,..) x,y... etc

It occurs to me, offhand, that post decrement and post increment are
the only instances of TERM OP.  Does this mean that post incrementing is
ugly?  :-)
