         - Range `[first, last)` is valid. Usually, this precondition cannot be checked efficiently. Only certain edge
           cases are detected; see the description of the exceptions above. A violation of this precondition yields
           undefined behavior.

-        A precondition is enforced with a runtime assertion that will result in calling `std::abort` if this
-        precondition is not met. Assertions can be disabled by defining `NDEBUG` at compile time. See
-        <https://en.cppreference.com/w/cpp/error/assert> for more information.
