Re: [boost] [Fit] formal review starts today

  Another (obscure) reason to be careful about
using inheritance:

#include <boost/fit/flip.hpp>

struct base { base(int) {} };

struct derived : virtual base {
    derived() : base(1) {}
    void operator()(int, void *) const {}
};

int main() {
    boost::fit::flip(derived())(nullptr, 2);
}

boost/fit/flip.hpp(56): error C2512: 'base::base': no appropriate
default constructor available
