hello all,

I get a compilation error with Boost.Operators and boost.Variant on vs2010:

struct KFoo : boost::totally_ordered<KFoo>
{
};

bool operator<(const KFoo&, const KFoo&);
bool operator==(const KFoo&, const KFoo&);

void Foo()
{
   boost::variant<KFoo> var;
   var.swap(var);
}

1>C:\work sdk\boost_1_57_0\boost/variant/detail/move.hpp(60): error C2668:

anyone?
