What if you want to store a modification of the value? e.g.
compatibility method to set a length in inches when the stored length is
in millimeters.
As outlined in my afterthought:
class Length
{
has Num $.mm is rw = 0;
method inch
{
yield $inch = $.mm * 25.4;
self.mm = $inch / 25.4;
}
}
Would you regard that as elegant?
