Discussion:
LWG 3631 modified the formattable concept. The new wording contains a small issue: basic_format_context requires two template arguments, but only one is provided.
[2023-05-24; Reflector poll]
Set status to Tentatively Ready after ten votes in favour during reflector poll.
Proposed resolution:
This wording is relative to N4944.
Modify 22.14.6.2 [format.formattable] as indicated:
-1- Let fmt-iter-for<charT> be an unspecified type that models output_iterator<const charT&> (25.3.4.10 [iterator.concept.output]).
[…] template<class T, class charT> concept formattable = formattable-with<remove_reference_t<T>, basic_format_context<fmt-iter-for<charT>, charT>>;
