Hi All

I'm trying to use std::vector::push_back() within a Boost.Lambda expression, but am finding it impossible
to bind correctly. Can anyone tell me what I'm doing wrong in this code?

Thanks in advance,

- Rob.

#include <vector>
#include <boost/function.hpp>
#include <boost/lambda/bind.hpp>

void f( )
{
    namespace ll = boost::lambda;
    using boost::function;

    typedef unsigned char Id;
    typedef std::vector<Id> Ids;

    ll::placeholder1_type x;

    Ids ids;
    void ( Ids::* push_back )( const Ids::value_type & ) = & Ids::push_back;

    function<void(Id)> my_push = ll::bind( push_back, ids, x ); // Line 18

    (void)my_push;
}
