If you really want to "equate to BASIC's" string functions,
then you will want to copy, as that's the real behavior of
BASIC.
If you use the non-copying version of Right, and subsequently
modify the resulting string value, you'll find that you've
also changed the original, due to sharing of the underlying
sequence of characters.
