    Unfortunately, function inlining is a bit more complicated than macro
preprocessor. The code after inlining is usually written in
intermediate language, and not in C/C++. The are two problems when you
do this in C/C++:
1. You sometimes need renaming of variables in order to create the
right code. For example
    inline ... f ... { x ... }
      ...
          T x;
    .. f (.... x ...) /* in some cases, x should be renamed */
2. If an inline function call appears inside an expression, you
sometimes need to break it to several parts, compute the function call
value, and use it in the computation of the expression. For example
    d=g(...f(...)...);
should usually be translated in C/C++ to
    {T reslt=f(...); /* expand f with the new var reslt */
      d=g(...reslt...);
    }
