A while back, I think I suggested that .{bytes,points,graphs,chars} be
defined to return an array with the contents of the string split into
the indicated pieces. If this was a tied array which updated the
underlying string, would we get the OP's behavior for free?
say $string.chars[-1];
$string.points.splice(0, 2, "Hello"); # Or "Hello".points
