It's unusual for a method to take an array of its arguments, rather than individual ones. Situation is something like a dispatcher; the methods already have defined arguments, say Widgets.search(widgetName, widgetCategory, widgetID). It'd be pretty weird for it to take an array containing those three arguments. The layer I'm talking about wants to call that, but only has an array of argument values, in order.
Not to be cranky, but while there's room for debate on why I want to do this, this isn't that conversation. If there's no more elegant approach than the switch strategy I mentioned, I'll probably ditch this entire route. I first wanted to check if anyone could think of a way to accomplish this in the CFML language, out of curiosity and to maybe learn something that might be useful some day, as well to get it done -- there's lots of smart and experienced folks out there. I didn't mean to discuss whether it's worth doing.
