[Boost-users] [bind] for_each, Member function question.

I have a question for boost:binders out there... In the following
scenario..(pseudocode)

Class Fred
{
 typedef std::map<wstring, shared_ptr<SomeType> > MyMap;

 MyMap Bert;

 Save(MyMap::iterator pos)
 {
    ...
 }

 SaveAll()
 {
    for_each(Bert.begin(), Bert.end(), bind(&Fred::Save, this, _1);
 }

};

The code wants to save all the data in the map. The bind, I was hoping,
would simply call Save for all items in the map, passing in the iterator
as the parameter, but I get a template compile fault on the bind. I've
tried all sorts of combinations, checked boost docs, read the chapter in
Beyond the C++ standard library, Googled etc, but just cannot figure out
what I need to do here.

Any help gratefully received.

James
