Really? It sure seems to be precisely an exception, in that it's an exception to the "normal" flow of control (e.g. return). Just because the type of what's thrown is called "Error" doesn't change the fact that they're conceptually exceptions (as opposed to, say, returning a boolean true/false to indicate an error).
In any case good to know I'm not off my rocker in thinking properties could throw except--errors.
