How to copy an object to separate allocated memory?

[Gary Willoughby via Digitalmars-d-learn]

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?
