#define DEFINE_LUA_PRIMITIVE_OP

(

Value:

template <class T> \
    class LUA_OPNAME(name) { \
      private: \
        LUA_OPNAME(name)() {} \
        void primitive(); \
    }

Defines a Lua primitive operation.

Note that just defining does not make much. One has to define operation cases for it to have any meaning.

Parameters:

name	- used to generate the operation name.
