That's a sneaky way to count lines :)
It might be worth pointing out that there are there are several text
modules that contain '_XS' in their name, such as Text::CSV_XS what
parse the file in C if your OS will support it, otherwise they use
pure perl. I am not as scientific as Chas so I will "guess" that
modules that use C will be faster.
