Hi All

I believe boost.bind has the capability to look through pointers and smart
pointers to
transparently process the pointed-to objects. Does boost.lambda.bind also
have this
capability?

I.e., this bit of code (and I am specifically using boost 1.37 for this btw)

#include <boost/lambda/lambda.hpp>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/construct.hpp>
#include <boost/shared_ptr.hpp>
#include <algorithm>
#include <vector>

struct A
{
    A( int );
    void f( );
};

int main( )
{
    using namespace boost::lambda;

    std::vector< A * > pv;
    std::vector< boost::shared_ptr< A > > sv;
    std::for_each( pv.begin( ), pv.end( ), bind( &A::f, _1 ) );
    std::for_each( sv.begin( ), sv.end( ), bind( &A::f, _1 ) ); // error
here.

}

Thanks,

- Rob.
