This prevents moving a single binding from the LHS variable of the assignment to another variable during the assignment process. - If a complex assignment tries to update a binding that already has its bit set then, the value of the binding is shallow-duplicated before proceeding. This ensures that the structure involved in the original complex assignment will not be mutated by further R level assignments during the original assignment process. For now, no attempt is made to unset the bit if the end of an assignment is not reached because of a jump. This may result in some unnecessary duplications. This could be prevented by maintaining a stack of pending assignments to resent the bits on jump, but that seems like overkill. It might also be useful to use this bit to communicate to functions when they are used in a getter/setter context. The bit used is bit 11 in the 'gp' field.
