I just wanted to point out that Nigel here was the guy who discovered
that the "my" technique was actually faster than the "Serge" technique of
directly calling a script object's properties and methods, (found by Serge
Belleudy-d'Espinose, of course).
repeat ( many ) times
-- In order of average best iterative speed:
--
get/set variableList's item x -- normal item access
get/set aReferenceToList's item x -- explicit saved reference
get/set myScript's propertyList's item x -- "Serge" access
get/set my propertyList's item x -- "Nigel" access
