--- Comment #6 from hst...@quickfur.ath.cx --- Good idea. However, it will break compatibility with the current Zip struct, which unfortunately is public so some user code out there may be naming it directly. Looks like we'll have to introduce a different overload of Zip for the compile-time StoppingPolicy variant. Code duplication galore. :-( --
