A basic principle that is related to magic numbers is that each truth your code bargains with should be declared just as soon as. If you utilize magic figures inside your code (including the password size case in point that @marcio gave, you can easily end up duplicating that point, and Whenever your have an understanding of of that simple fact changes you have a servicing problem.
std::initializer_list needs compiler aid and can't be reimplemented as Yet another course (in terms of I am aware), nevertheless I'm unsure if it counts because it's in c++0x.
