Right.  I'm not sure why you would want to operate directly on
octave_value objects unless you were working on a simple Octave to C++
translator or if you are trying to write some generic functions in C++.
(For example, C++ code that can do the equivalent of something like:

  function result = add (a, b)
    result = a + b;

and not have to do any type checking/value extraction before
attempting the addition.)

If you are writing generic functions, why not just write them in the
scripting language?

If you are working on a translator, then it might be useful to share
some of your ideas on the list.
