  call-by-name
       
          (CBN) (Normal order reduction, leftmost, outermost reduction).
          An argument passing convention (first provided by ALGOL 60?)
          where argument expressions are passed unevaluated.  This is
          usually implemented by passing a pointer to some code which
          will return the value of the argument and an environment
          giving the values of its free variables.  This evaluation
          strategy is guaranteed to reach a normal form if one
          exists.
       
          When used to implement functional programming languages,
          call-by-name is usually combined with graph reduction to
          avoid repeated evaluation of the same expression.  This is
          then known as call-by-need.  The opposite of call-by-name is
          call-by-value where arguments are evaluated before they are
          passed to a function.  This is more efficient but is less
          likely to terminate in the presence of infinite data
          structures and recursive functions.  Arguments to macros
          are usually passed using call-by-name.
