Thank you kindly Roman, that helped - and is obvious now that I see it, 
again many thanks.

I do however have one more boost::bind question that I can't quite get 
myself around.

I want replace the following for-loop with a call to std::for_each, and 
am near certain that bind would do it:

std::list<boost::tuple<int, float, std::string> > li;

...

for (std::list<boost::tuple<int, float, std::string> >::iterator it = 
li.begin(); it != li.end(); ++it)
{
     // this is ok - is all part of a class that inherits from MyFunctor

     MyFunctor::operator()(boost::get<0> (*it));
}

How might I convert the above to something using std::for_each, and 
boost::bind?

Again, with thanks in advance
