In some cases, sure. But without some exceptionally creative use of expression templates, you'd have a situation where the ordering of variables determine the validity of the expression - and even then, any extra precision that the implementation uses (e.g. for floating point arithmetic) would probably be lost (and if it's not lost, predictability will suffer).
