ive got a list with several objects... id like to call a member function for each of these objects with boost lambda... instead of for (...) list[n].Foo(); id like for_each(list.begin(), list.end(), ???); how would i do that?

You don't need boost.lambda for that, the standard library provides:

for_each(list.begin(), list.end(), std::mem_fun_ref(&Type::Foo) );

#include <boost/bind.hpp>

std::for_each(m.begin(), m.end(), boost::bind(&Type::Foo, boost::bind<Type&>(&std::map<int, Type>::value_type::second, _1)));
