Consider that some inductances that I use are not symmetric. While I don't know of any asymmetric resistors (but maybe they exist), some microwave broadband inductors are asymmetric (you can't swap pins 1 and 2, as for polarized capacitors): http://www.piconics.com/Conicals.html Coilcraft has similar products. In other ways, for two terminal components, some are symmetric dipoles, others are asymmetric. Diodes might fall in the second category, but diacs might fall in the first.
