I am very sorry for that, I did not want to hurt you; I was too rude.
This just shows how far I am from your practice of C++ because the
fact that I understood the operator, trick did not make me think of
how to use it to perform what I wanted. I have now read carrefully
your proposed code and it works!
I am now able ot  make the has_operator_xxxx traits work for any
return type. So thank you very much and many kudos for your kind help.
