In terms of raw performance for small computing tasks, your solution is much better. I believe that for larger computing tasks, which is arguably more realistic for games or CAD, the PDL solution is competitive in both computing performance, and especially ease of programming and maintenance.

Probably the greatest utility in the above example is just showing how to approach this class of problems with PDL, and doing so prompted me to add a couple of arguably missing features to PDL.
