> I was looking at some of the implementations of DeferredObject. I found that some carry
two extra-properties:
> boolean eager;
> boolean eval;
> Where eval is used to track if the obj is initiated. My thinking is that these extra
properties make the objects "fat" and if removed it allows us to fit more lazy objects in
the same memory.
