The purpose of this repository is to supply an implementation of most of the operators in the Conses dictionary of the Common Lisp standard.
We value performance, but we value correctness and maintainability even more. We do not think it is important to optimize the implementation of an operator that is not used very often. While we do not know a priori how often an operator might be used, we think that for an application that uses an operator very often, and where our implementation of that operator does not have the best performance, the application writer is very likely to implement a special version anyway that takes into account the specific needs of that application.
