@ -73,15 +73,8 @@ struct iterator_writability_disabled
// Convert an iterator_facade's traversal category, Value parameter,
// and ::reference type to an appropriate old-style category.
//
// If writability has been disabled per the above metafunction, the
// result will not be convertible to output_iterator_tag.
//
// Otherwise, if Traversal == single_pass_traversal_tag, the following
// conditions will result in a tag that is convertible both to
// input_iterator_tag and output_iterator_tag:
//
// 1. Reference is a reference to non-const
// 2. Reference is not a reference and is convertible to Value
// Due to changeset 21683, this now never results in a category convertible
// to output_iterator_tag.
