I want to keep def as a class constant.</p><p><a href="https://social.chaotikum.org/tags/cpp20" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cpp20</span></a> <a href="https://social.chaotikum.org/tags/gcc" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gcc</span></a> <a href="https://social.chaotikum.org/tags/clang" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>clang</span></a></p>
