To be honest I don't know C++ generic rules enough, but just note that they 
are different from Fortran and we must ensure that any rules are consistent 
with Fortran. You cannot, and should not, simply cut and paste the C/C++ 
bindings and just replace a few keywords because the rules for generic 
disambiguation should be taken into account. We can discuss more technically 
when there is a specific proposal.
Best,
Aleks
