The difference between shared and not-shared is that shared constructors 
run once per program, whereas non-shared constructors run once per thread.

This is D1, so likely it's equivalent to running shared constructors. 
But it depends on whether there are multiple threads.

There is no feature right now that allows you to mark a ctor as 
standalone. But the compiler will mark some of them as standalone if it 
can determine that it's that way.
