TJ,
IMHO this is an EXTREMELY important feature without which serious
developers find their hands continually tied as it's at best
difficult to develop "adaptive" systems.

I have had to resort to manually coding each indicator/function in
script, and script sucks. Error messages while debugging are so
vague, that they are useless.
