I haven't done benchmarking, either, but I've seen them in the past. Slurping is by far faster than processing line-by-line. Reason is that doing I/O in a single operation is faster than doing a bit at a time, since you don't have to worry about things like resetting the drive head to the correct position.

Naturally, you have to worry about memory limitations. There is really a limited number of cases when slurping is worth it. If your file is small enough to fit in memory, you won't see much speed gain. If it's too large, you'll end up swapping to the hard disk and will thus lose any benifits from slurping.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
