The main difference is that function `safenext()` and `complete()` are replaced with one another iterator `PrefetchIterator` which constantly keeps 1 element in cache, making it available for comparison without actually moving an iterator pointer (see [this comment](https://github.com/JuliaLang/Iterators.jl/pull/62#discussion_r65936235) for details why it is needed at all). Compared with #62, this version:\r\n\r\n * is more type stable (assuming type stable iterator)\r\n * cannot handle empty iterators (since `PrefetchIterator` reads 1 element during construction)"},"comment":{"url":"https://api.github.com/repos/JuliaLang/Iterators.jl/issues/comments/224799858","html_url":"https://github.com/JuliaLang/Iterators.jl/pull/63#issuecomment-224799858","issue_url":"https://api.github.com/repos/JuliaLang/Iterators.jl/issues/63","id":224799858,"user":{"login":"mschauer","id":1923437,"avatar_url":"https://avatars.githubusercontent.com/u/1923437?v=3","gravatar_id":"","url":"https://api.github.com/users/mschauer","html_url":"https://github.com/mschauer","followers_url":"https://api.github.com/users/mschauer/followers","following_url":"https://api.github.com/users/mschauer/following{/other_user}","gists_url":"https://api.github.com/users/mschauer/gists{/gist_id}","starred_url":"https://api.github.com/users/mschauer/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mschauer/subscriptions","organizations_url":"https://api.github.com/users/mschauer/orgs","repos_url":"https://api.github.com/users/mschauer/repos","events_url":"https://api.github.com/users/mschauer/events{/privacy}","received_events_url":"https://api.github.com/users/mschauer/received_events","type":"User","site_admin":false},"created_at":"2016-06-09T04:56:01Z","updated_at":"2016-06-09T04:56:01Z","body":"I think ``!isnull && done == last`` so you could get rid of ``last``"}}
