Hi,

I'm looking to use a trait in enable_if that can distinguish between a  
raw pointer and any other valid iterator type, essentially the  
difference between iterator traits and the raw pointer specialization.

template <class Iterator>
struct iterator_traits;

template <class T>
struct iterator_traits<T*>;

I was hoping to find a boost::is_iterator type trait which would  
return false_type for is_iterator<int*> (any raw pointer) and true  
type for any other valid iterator.  This would allow me to group  
iterators via is_pointer and is_iterator.  I was just wondering if  
this already exists somewhere?

Thanks.
