User:Kevin Reid/Common Lisp tasks

This is Kevin Reid's personal classification of tasks not implemented in Common Lisp, or just poorly done in CL, by what kind of problem they are.

If you wish to help update this list, please do only these:

• Add new tasks to #To classify.
• Move completed tasks to #Completed; I will review them.

As of 18:19, 12 August 2009. When updating this list, consult the main unimp list's diffs since then for what to add/move.

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.
• Simple Windowed Application — Should be reviewed for niceness by a CLIM expert.
