Note: in case you wonder and before you point it out... since this has directly or indirectly to do with some sort of optimisation: yes, I know that "premature optimisation is the root of all evil", and I'm asking just out of curiosity!

It's called "XS". :-) It's hard to understand, has a bunch of odd little rules and quirks, and makes the relevent perl function typically run several times faster than the more straightforward encoding.

It's also a right pain to debug and maintain, again, like Duff's device, and other assorted hackery and trickery. ;-)
