says that the dynamic loader is responsible for determining the
order in which the constructors have to run. The constructors
for all dependencies of an object must run before the constructor
for the object itself. Circular dependencies are left unspecified.
This is highly questionable since it puts the burden on the dynamic
loader which has to find the dependencies at runtime instead of
letting the user do it right. Stupidity rules! */
