To improve

• Basic bitmap storage#Common Lisp — review for efficiency (inlining?), necessity of type declarations, idiom
• Adding variables to a class instance at runtime#Common Lisp — This should be a per-*instance* change. Use the MOP to generate a subclass and change-class to it.
• Arithmetic Evaluator#Common Lisp — I think there could be some simplification by changing to a prefix AST and using the CL operator names (use symbol-function, not eval).
• Pattern Matching#Common Lisp — See if there's a pattern matching library that offers more-lispy syntax.
• Basic Animation and Pendulum Animation — Investigate using CLIM.
