Or wrap its use with 3 :'' or 4 :'' Explicit definitions add at least five characters (perhaps more, if your expression uses quotes or appears to the right of some number), but sometimes you have to spend more than that working around the pre- or post- processing issues. Explicit definitions add some parsing overhead, but this overhead is generally orders of magnitude less than the interpreter overhead associated with recursive functions.
