Idio Object System

The Idio Object System is derived from Gregor Kiczales’s Tiny CLOS and provides:

• classes with instance slots

• multiple-inheritance

• generic functions with multi-methods

• primary methods and next-method

IOS differs from many familiar object-oriented systems in that classes and the functions that operate on them are separated.

On the one hand you define classes with named fields and optional super-classes and on the other hand you define generic functions and associate with those generic functions methods with particular argument specializers (classes).

When a generic function is invoked with some arguments, the most specific method for those arguments is invoked which can call the next most specific method should it need to.

The computation of the most specific method (and the increasingly less specific methods in turn) uses all the arguments to the generic function not just the one (usually the first) as in other systems.
