I agree with you, when you say that BOOST_NON_DERIVABLE macro is not useful with structures, since it introduces a great overhead. I was obliged to introduce that virtual functions, in order to fix a bug of the first version, but maybe I will find an alternative solution.
Please don't top post. Maybe you could have both implementations available? That way a user could decide to do struct point : BOOST_NON_DERIVABLE { /* whatever */ }; or class Foo : public Bar, BOOST_NON_DERIVABLE_MI { /* whatever */ }; Not the prettiest, and the first example is not immune to subsequent design changes, but that could be mentioned in the docs... The best solution would obviously be a single one that works correctly in all situations. Good luck! --Michael Fawcett
