I use these extensions to "for_each" alot.  You can add them to your
list if you want.

template<typename _InIt, typename _InIt2, typename _Fn1> inline
_Fn1 for_each(_InIt _First, _InIt _Last, _InIt2 _First2, _Fn1 _Func)
{	
        for (; _First != _Last; ++_First,++_First2)
                _Func(*_First,*_First2);
        return (_Func);
}

template<typename _InIt, typename _InIt2, typename _InIt3, typename _Fn1> inline
_Fn1 for_each(_InIt _First, _InIt _Last, _InIt2 _First2, _InIt3
_First3, _Fn1 _Func)
{	
        for (; _First != _Last; ++_First,++_First2,++_First3)
                _Func(*_First, *_First2, *_First3);
        return (_Func);
}

template<typename _InIt, typename _InIt2, typename _InIt3, typename
_InIt4, typename _Fn1> inline
_Fn1 for_each(_InIt _First, _InIt _Last, _InIt2 _First2, _InIt3
_First3, _InIt4 _First4, _Fn1 _Func)
{	
        for (; _First != _Last; ++_First,++_First2,++_First3,++_First4)
                _Func(*_First, *_First2, *_First3, *_First4);
        return (_Func);
}

template<typename _InIt, typename _InIt2, typename _InIt3, typename
_InIt4, typename _InIt5, typename _Fn1> inline
_Fn1 for_each(_InIt _First, _InIt _Last, _InIt2 _First2, _InIt3
_First3, _InIt4 _First4, _InIt5 _First5, _Fn1 _Func)
{	
        for (; _First != _Last; ++_First,++_First2,++_First3,++_First4,++_First5)
                _Func(*_First, *_First2, *_First3, *_First4, *_First5);
        return (_Func);
}
