Gabriel,

Thanks for pointing that out! I had completely forgotten about
that!

I've tested them before. readlines() is very slow. The deprecated
xreadlines() is close in speed to open() as an iterator. In my particular
test, I found the following:

readlines() -> 32 "time units"
xreadlines() -> 0.7 "time units"
open() iterator -> 0.41 "time units"
