From my understanding, the idea behind the std::format framework would be to
have a “cardinality" type for which we can implement a special formatter,
allowing “whatever” to be in the format specification.

Still supporting all the standard format specifications for integers is then an
exercise I didn’t try.

Always good to remind the committee that user interfaces are a thing ;)
