This is the crux of it. If this condition really does represent a
programmer error (and IMO in this case it does), then Matt is right.
Throwing is wrong. Programmer error == bug == your program is already in
some weird state. Continuing by throwing an exception and executing an
arbitrary amount of code is not good.

Precondition violations ==> assertions. Use BOOST_ASSERT. That gives
people a way to hook the behavior while giving a sane default.
