Because program objects are used to model the mathematical ones. The
mathematical fact that circle is an ellipse makes possible
substitutability (limited of course) of the corresponding model
objects in programming language, which in turn is the basis of code
reuse.

So what? All values are immutable as well. If you think that
immutability implies absolute substitutability, then you are wrong. It
is a common delusion.

If you do not like Circle and Ellipse, take int and float in C++.
