Imagine the following:

struct foo { bar& operator[](int); bar& operator[](std::string); } Foo;

boost::variant Idx;

Is some simple way exist to apply foo::operator[](T) for Foo and Idx?

Something like boost::apply_visitor(boost::bind(&foo::operator[], boost::ref(Foo), _1), Idx); // does not compile

You can either use a combination of bind and lambda: (untested) boost::bind(boost::lambda::ret(boost::lambda::var(Foo)[boost::lambda::_1]), _1); or you can write your own function object In Christ, Steven Watanabe
