Overview

Special class to represent any entity of a type. This is used for type-wide grants or checks. It is basically so AllOfType can have an entity rather than a nil.

Wildcards or null objects typically have somewhat strange semantics, and this is no exception. It will compare as eql? and == to any object that has the same type attribute.
