Résumé
Coloring is an implementation technique for multiple inheri- tance which is as efficient as single inheritance but only works in a global compilation or global linking framework. In this short paper we propose a variation on coloring that makes it compatible with shared libraries. Our proposal is usable for method invocation, attribute access, and subtype check, and respects five functional and efficiency requirements: constant time, quadratic space, short code, compatible with multiple inheritance, and incremental. We validate our proposal with theoretical evaluations, simulations and real executions which all show that the overhead for shared libraries remains small.
