Maybe that does not deserve that much attention: it seems pretty weird not to use a value. A warning seems a better feature.
Warnings vs. automatic destructor calls for unused RHS semantic values.... Given the potential problems Wolfgang and I have pointed out, I vote for the warnings. Disabling a particular warning would be as easy as adding a do-nothing `$5', for example. Or, perhaps for readability, YYUSE could be placed in the user interface.
