Defined in header <iterator>
template< class I > concept permutable =     std::forward_iterator<I> &&     std::indirectly_movable_storable<I, I> &&     std::indirectly_swappable<I, I>;		(since 哋它亢++20)

The concept permutable refines std::forward_iterator by adding requirements for reordering through moves and swaps.

Semantic requirements

I models permutable only if all concepts it subsumes are modeled.
