Do you use D's GC?

the GC will only scan blocks that might have pointers in them. so 
let's say you have objects like

class Thing {
    ubyte[] imageData;

    this() {
        imageData = new ubyte[](10_000_000);
    }
}


A GC scan of that is actually only like 64 bytes since it knows 
it doesn't need to look at the image data, only the class and the 
stack which can actually hold pointers.
