All iterators are "rewindable", though of course not in practice. I would avoid such names because we may eventually add an interface which works as a "tag" to say "yes, I actually do support rewinding." The property of being rewindable comes from it being cached. Maybe `CachedAggregate`? Aggregates are data structures from which an external iterator can be obtained, so it makes a bit more sense if it's eager. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
