I've never understood the line-count craze some people get on. If it was that important, we'd all be using J or APL. Since we're not — in fact, almost nobody is — it must not be that critical.
Fallacy. You haven't eliminated the possibility that line count is important, but also that too few lines is also bad. It's widely understood that line count, even though it's a hazy and exploitable metric, is indeed important. It's also widely understood that being too terse is as bad as being too verbose. Time to brush up on some old-school CS curriculum books. (Mythical Man-Month? I'm not sure if the above is discussed there, but it's a good place to start.)
Now, wasn't it more enjoyable the way I put it first?
