 * \param E The element type. This type is the element in the underlying sequence
 * \param V The value type. This is the type to which the element type is translated
 * \param T The traits_type. This type provides a static method \c make_value(), which
 * converts the element type to the value type
 *
 * \deprecated This is maintained for backwards compatibility with the
 *   recls/COM library. New users should instead use
