ClassyTcl is a dynamically loadable object system for Tcl. Both a Tcl-only and a C implementation are available. It also doesn't require patches to the Tcl core, which makes installation and maintenence easier. Performance is quite adequate. The C version is gives extra speed, and makes it possible to implement some methods in C. In contrast to other object systems for Tcl, it is not modeled after the object system designed for a completely different language, such as C. The system is simple but flexible. Classes and objects are dynamic, and can easily be queried, changed, and debugged at runtime.
