   *  @since C++23
   *  @headerfile functional
   *
   *  The `std::move_only_function` class template is a call wrapper similar
   *  to `std::function`, but does not require the stored target function
   *  to be copyable.
   *
   *  It also supports const-qualification, ref-qualification, and
   *  no-throw guarantees. The qualifications and exception-specification
   *  of the `move_only_function::operator()` member function are respected
   *  when invoking the target function.
