Nested requirements are used to specify requirements on type parameters.
Typically, you use a requires expressions to define a concept, but they can also be used as a standalone feature when a compile-time predicate is required. Therefore, use cases for requires expression can be a requires clause,
constexpr if. I will write in my next post about these special use cases of requires expressions.
