-Just as an ordinary class defines the behavior of certain objects, a metaclass defines the behavior of certain classes and their instances. Not all object-oriented programming languages support metaclasses.
-Among those that do, the extent to which metaclasses can override any given aspect of class behavior varies.
-Each language has its own metaobject protocol, a set of rules that govern how objects, classes, and metaclasses interact.
-Often [[Namespaces]] are used as identifiers in Metaclasses, to distinguish different classes.
