All arithmetic operations on integer types (including bitwise manipulations) 
operate on the original type or (u)int (whichever is larger). So, if you want 
to manipulate a ubyte and then assign the result to a ubyte, you need to cast 
it. It's the same with C/C++ except that C/C++ just silently do the cast for 
you, whereas D requires an explicit cast for narrowing conversions.
