Sed, awk, tr and a number of other unix utilities are, perhaps 
fortunately, used comparatively seldom these days. Since the command 
lines are notoriously cryptic, I think there's a strong argument for 
keeping individual stages of a filtering operation as simple as 
possible; this also allows stages to be lopped easily for debugging.


And that particularly applies in a context where a significant 
proportion of readers don't use unix, and have no inclination to try.
