Just for those interested, I was bored and did a loop speed test of mzscript vs lslua. I moved a small label 1px at a time across the screen (1600px) and back. I used a similar loop script for mzscript as above, and I used the repeat until loop for lslua. (The site wouldn't let me paste the code...you would think the code tags would let you paste things explicitly. :P )

This probably won't come as a surprise to the real coders out there, but lslua blew away mzscript. For this test, lslua was clearly faster when running its loops, showing an obvious speed increase in the label's movement.
