that won't fit in a byte btw.


The rest of the assignment stuff is easy. I'd prolly even do it 
with a template:

this(T)(T t) { this.opAssign(t); } // for construction
Byte opAssign(T)(T t) if(T.sizeof == 1) { // for other assignment
     data_holder = cast(typeof(data_holder) t);
}

and that should do it.

Language won't let you do these though.
