Confused (as always), David.  Your definition is 77 characters, mine is 
56.   I assume that the "bytes saved" must therefore be in TeX's 
internal memory, but we have for quite some time not been restricted to 
640kB, so are there any real-world situations in which saving those few 
bytes (and some expansion steps) is more important that writing clear, 
simple, didactic code ?
