The funny thing about your newly defined "trick" is that it would be foolish to rely on such undocumented behavior not changing on the next minor update. :)
Well the same applies to this definition of "trick" so I'm not sure that's a particularly damning point.
Either way, I didn't say such "tricks" are without peril - surely a number of jQuery "tricks," even those that were eventually canonized, have been broken over the years as the library updates.
