Great. This pushes the pure version up a notch.
I've updated the wiki, showing how the code has progressed:
Author Time in seconds (N=10)
Original entry: > 2 minutes
Sebastian Sylvan: 15.4
Kimberley Burchett: 7.2
Cale Gibbard: 5.8
Bertram Felgenhauer: 4.7
Original impure 2.1
Fastest pure 1.8
Fastest impure 1.4
And comparison with the C version:
C gcc 1.35
C gcc -O2 0.5
