Symbolic endpoints are probably a bad idea. The complexity of the
endpoint expressions grows very fast.
Building a CAS from scratch on top of some generic-arithmetic
object-oriented math-hierarchy framework
is a perennial project that works up to a point and then tends to fall
apart for a variety of reasons.
Finding a single organizing principle is not so hard. Finding one that
works is harder..
