But it /is/ a collection of lines.  And it works just fine without an
intermediate array.  What I'm saying is that you may have to retrain
your mind to get it to understand that a collection can be represented
by other things than a plain-ol' array.

I realize that you know what I'm saying above, but I figured I'd drive
my point home in a concise manner as well.
