It's not just globals with constructors and the order is not obvious. For example, few people (including yours truly) realize the whole complexity of the code like this: const float epsilon = 0.001f; const float one_sup = 1.f + epsilon; const float one_inf = 1.f - epsilon; I once spent a day trying to figure out what's going on when similar code suddenly (like after several years of constant use without any issues) broke.
