Compact Dispatch Tables for Dynamically Typed Object Oriented Languages

Dynamically typed object-oriented languages must perform dynamic binding for most message sends. Typically this is slow. A number of papers have reported on attempts to adapt C++-style selector table indexing to dynamically typed languages, but it is difficul to generate space-efficient tables. Our algorithm generates considerably smaller dispatch tables for languages with single inheritance than its predecessors at the cost of a small dispatch time penalty.
