How can you copy (clone) a string?

Um ... yes and no.

Whilst the *current* compiler treats it as a runtime computed string, there
is not reason that a future compiler need do so. As strings are immutable,
and 2*'a' is a trivial calculation (it is only reliant on constants) the
compiler could well decide to change this to 'aa' i.e. a compile-time
computed string.
