   Modern Fortran might be the easier way, because a change can be done   
   incrementally, and this...

   ... would not be an issue.  What features is modern Fortran missing that   
   you need C++ for?

   If I remember correctly, it does so by issueing invalid C (or   
   C++), by using negative offsets from pointers.  Might work now,   
   might not work tomorrow.   
      
   But note the IIRC above.
