  //  Operators
  //
  //      Lazy operators
  //
  //      This class provides a mechanism for lazily evaluating operators.
  //      Syntactically, a lazy operator looks like an ordinary C/C++
  //      infix, prefix or postfix operator. The operator application
  //      looks the same. However, unlike ordinary operators, the actual
  //      operator execution is deferred. (see actor.hpp, primitives.hpp
  //      and composite.hpp for an overview). Samples:
  //
  //          arg1 + arg2
  //          1 + arg1 * arg2
  //          1 / -arg1
  //          arg1 < 150
  //
  //      T1 set of classes implement all the C++ free operators. Like
  //      lazy functions (see functions.hpp), lazy operators are not
  //      immediately executed when invoked. Instead, a composite (see
  //      composite.hpp) object is created and returned to the caller.
  //      Example:
  //
  //          (arg1 + arg2) * arg3
  //
  //      does nothing more than return a composite. T1 second function
  //      call will evaluate the actual operators. Example:
  //
  //          int i = 4, j = 5, k = 6;
  //          cout << ((arg1 + arg2) * arg3)(i, j, k);
  //
  //      will print out "54".
  //
  //      Arbitrarily complex expressions can be lazily evaluated
  //      following three simple rules:
  //
  //          1) Lazy evaluated binary operators apply when at least one
  //          of the operands is an actor object (see actor.hpp and
  //          primitives.hpp). Consequently, if an operand is not an actor
  //          object, it is implicitly converted to an object of type
  //          actor<value<T> > (where T is the original type of the
  //          operand).
  //
  //          2) Lazy evaluated unary operators apply only to operands
  //          which are actor objects.
  //
  //          3) The result of a lazy operator is a composite actor object
  //          that can in turn apply to rule 1.
  //
  //      Example:
  //
  //          arg1 + 3
  //
  //      is a lazy expression involving the operator+. Following rule 1,
  //      lazy evaluation is triggered since arg1 is an instance of an
  //      actor<argument<N> > class (see primitives.hpp). The right
  //      operand <3> is implicitly converted to an actor<value<int> >.
  //      The result of this binary + expression is a composite object,
  //      following rule 3.
  //
  //      Take note that although at least one of the operands must be a
  //      valid actor class in order for lazy evaluation to take effect,
  //      if this is not the case and we still want to lazily evaluate an
  //      expression, we can use var(x), val(x) or cref(x) to transform
  //      the operand into a valid action object (see primitives.hpp).
  //      Example:
  //
  //          val(1) << 3;
  //
  //      Supported operators:
  //
  //          Unary operators:
  //
  //              prefix:   ~, !, -, +, ++, --, & (reference), * (dereference)
  //              postfix:  ++, --
  //
  //          Binary operators:
  //
  //              =, [], +=, -=, *=, /=, %=, &=, |=, ^=, <<=, >>=
  //              +, -, *, /, %, &, |, ^, <<, >>
  //              ==, !=, <, >, <=, >=
  //              &&, ||
  //
  //      Each operator has a special tag type associated with it. For
  //      example the binary + operator has a plus_op tag type associated
  //      with it. This is used to specialize either the unary_operator or
  //      binary_operator template classes (see unary_operator and
  //      binary_operator below). Specializations of these unary_operator
  //      and binary_operator are the actual workhorses that implement the
  //      operations. The behavior of each lazy operator depends on these
  //      unary_operator and binary_operator specializations. 'preset'
  //      specializations conform to the canonical operator rules modeled
  //      by the behavior of integers and pointers:
  //
  //          Prefix -, + and ~ accept constant arguments and return an
  //          object by value.
  //
  //          The ! accept constant arguments and returns a boolean
  //          result.
  //
  //          The & (address-of), * (dereference) both return a reference
  //          to an object.
  //
  //          Prefix ++ returns a reference to its mutable argument after
  //          it is incremented.
  //
  //          Postfix ++ returns the mutable argument by value before it
  //          is incremented.
  //
  //          The += and its family accept mutable right hand side (rhs)
  //          operand and return a reference to the rhs operand.
  //
  //          Infix + and its family accept constant arguments and return
  //          an object by value.
  //
  //          The == and its family accept constant arguments and return a
  //          boolean result.
  //
  //          Operators && and || accept constant arguments and return a
  //          boolean result and are short circuit evaluated as expected.

  //
  //  Operator tags
  //
  //      Each C++ operator has a corresponding tag type. This is
  //      used as a means for specializing the unary_operator and
  //      binary_operator (see below). The tag also serves as the
  //      lazy operator type compatible as a composite operation
