We identify three design principles for reflection and metaprogramming facilities
in object oriented programming languages. Encapsulation: meta-level facilities must
encapsulate their implementation. Stratification: meta-level facilities must be
separated from base-level functionality. Ontological correspondence: the ontology
of meta-level facilities should correspond to the ontology of the language they
manipulate. Traditional/mainstream reflective architectures do not follow these
precepts. In contrast, reflective APIs built around the concept of mirrors are
characterized by adherence to these three principles. Consequently, mirror-based
architectures have significant advantages with respect to distribution, deployment
and general purpose metaprogramming.
