I have been trying (again) to start using const and immutable objects in
a project, and found I kept getting stuck with the need to change the
value of object references, which isn't allowed. I don't quite follow the
arguments that mean that this has to be the case, but I'm prepared to
accept them.
After some experimenting with Andrei's Rebindable template, I still
couldn't get past the problems. For a start, the get method is private so
I couldn't test for null.
In the end I cooked up the following, which is a very simple workaround
that just lets me assign to a const or immutable object reference. It
works just fine, and can be used in templates like containers without
forcing the container to care about what it is containing.
Comments?

Hi Graham,
Could you please post a short snippet (or a few) that illustrate the
problems you ran into with Rebindable?
Thanks,
Andrei
