Componere (latin, English: compose) targets production environments and provides an API for composition of classes, monkey patching, and casting.
Componere\Definition is used to define (or redefine) a class at runtime; The class can then be registered, and in the case of redefinition it replaces the original class for as long as the Componere\Definition exists.
Componere\Patch is used to change the class of a specific instance of an object at runtime; Upon application the patch will remain applied for as long as the Componere\Patch exists, and can be reverted explicitly.
Componere\ casting functions can cast among user defined compatible types;
Where compatible means Type is sub or super to the type of object.
