What is gained by having it in Fortran instead of C++?  If there is no
particular advantage to using Fortran, then I guess I would prefer to
have most code in C++.  You mentioned the performance problem for
signals, but I think it is fairly easy to eliminate that problem
problem in C++ with a few macros.  I'd rather avoid the duplicate
code.  Doing that with sed, awk, or m4 is possible, but adds some
complexity to the build system that we don't have with C++ templates.
OTOH, C++ templates add some complexity to the code.  I don't see that
there is one strict set of rules that we can write down for what is
best in all cases.
