This leads into the an new field:

            programming via suggestions and hints

I suppose if you really want assignment you can do it
explicitly with the old syntax.  If you know that you really
want mutation, you can use the method call to make it explicit.
That way you get the proper error if you try to mutate an
immutable object.
