I was reading Ali's book (http://ddili.org/ders/d.en/index.html) and saw this piece of code on how to get the true size of an object:

MyClass* buffer = cast(MyClass*)GC.calloc(__traits(classInstanceSize, MyClass) * 10);

That got me thinking, how would i actually 'fill' this memory with instances of that class?
