Tom, what kind of scripts/tools were you using to measure this 1.3 -> 1.5
speed improvement? I have not found much "demo code" that was easy
to use with Jacl for the testing runtime performance issues. One could always
write a small loop and use time {...} to measure it, but that does not really
work like "real world" Jacl code. I guess what I am really looking for is some
number of Jacl examples that do more than just a simple loop and yet can
easily be used outside of other code to test the Jacl runtime impl.
