max_of, reduce_of, pause, item_map, etc.
5) New named ILEs: at, call,
create, get, id & mcall.

Castor is a pure C++ header Library that introduces the Logic paradigm into C++.
Castor integrates the Logic Paradigm using a few simple library primitives. This
unique approach not only allows a natural and deep integration of declarative
code into C++, but also provides the flexibility of combining Logic with other
paradigms natively supported by C++ such as OOP, generics etc. STL concepts like
iterators, containers and streams can also be used in declarative code.
