I would be curious to know why the standards committee decided not to
allow pointers to members as initializers inside classes. It seems
like it would always be a constant that could be computed at compile
time -- but maybe I'm missing something. I can, perhaps, understand
why it is not allowed within the class as the class is being defined
(or declared). But, relative to all the other hard things that a C++
compiler has to figure out at compile time, that seems relatively
simple as well.
