Enforcement would require some knowledge about what in the header is meant to be “exported” to people and what's there to help implementation.

By reusing s (handed by reference), we allocate new memory only when we must grow s’s potential.
Forgetting a case normally transpires any time a situation is additional to an enumeration and the person doing so fails to add it to each
Join your threads! (because of std::terminate in destructor if not joined or detached … is there a great rationale to detach threads?) – ??? could support library give a RAII wrapper for std::thread?
It should be probable to name a operate meaningfully, to specify the necessities of its argument, and Evidently state the relationship concerning the arguments and the result.
