[boost] Re: container traits

I don't have many suggestions for container traits, but I would like to see
an additional iterator trait, denoting whether or not the dereferencing of
the iterator results in a reference (or constant reference for non-mutable
iterators).

i.e.:
template <class Iterator>
struct iterator_trait_is_reference
{
  static const bool is_reference = false;
};
template <class T>
struct iterator_trait_is_reference<T *>
{
  static const bool is_reference = true;
};

The presence of this trait would allow some (inplace) algorithms (like
iter_swap) to be more efficient.
