The compose module is a mixin based object composition factory, features powerful and robust object creation and deterministic multiple inheritance, notably it DOES NOT use prototype chain for inheritance, which eliminates unexpected modification from prototype chain, and being more performant.

Extend

The factory assists in composing both constructors or instances, by consuming a specification object, by mixing in all properties found in object onto the original and return a new constructor.

Composite

Factory can be quite flexible, one or more specs or constructors can be passed as arguments, ordered from left to right, with the ones comes later taken precedence (overriding) over the former.

Besides of regular object composition feature, the factory also introduces a few necessary features for building TroopJS component:

• Decorators are convenient method override eliminating the need for super call;
• Specials are irregular functions for describing reactive component behaviors, aka. event listeners.
