Right on msakrejda, thank you very much!
Interesting (at least to a noob like me): apply() turns out to be a method of the top level Function class. When you type 'Math.max.' or 'Math.max().' in the code, that last dot does not trigger code assist in FlexBuilder.
The moral of the story: you better spend some time delving into this AS language.
Math.max is static, so the first argument can't possibly matter, right?
