I have a class, rclass.  It has an attribute value.  Can I arrange
so that the string
    r1=r2
sets r1.value to equal r2.value (where r1 and r2 are class instances,
of course) without changing anything else about r1?  I'm willing to
test, say, that r1.classtype==r2.classtype or something, first to make
sure the assignment is sensible.

And if so, can I also have r1=7 set r1.value to be 7?

I want to have a box in a GUI where users can enter code, such as
assignments, and I'd like to avoid the reference to the underlying
attribute.

Thanks,
