modify in place

[Ben Sapp]

How can I modify a variable that is a new user defined type?  I want to
modify the actuall variable.  I do not want to make another modified
instance of the variable.  I tried the following piece of code and it
compiled fine but, ended up crashing on the line in
"non_const_function()" where I modify some internal variables in
myclass.  

------------------------------------------------------------
octave_value &rep = const_cast<octave_value&>(args(0).get_rep());
octave_myclass &myclass = (octave_myclass &)(rep);
myclass.non_const_function();
-------------------------------------------------------------

I want it to work like this from the octave command line:

modify_in_place(a);

Now "modify_in_place" does not return any thing it just changes the
value of "a".  

Thanks.
