I don't think any behavior is changed, but please take a look.\r\n\r\n@simonster I had to change some tests of reductions on empty arrays that you wrote. It used to be the case that `minimum` and `maximum` of empty arrays were empty, but with my changes they are `typemax` and `typemin` respectively. Have we discussed this before? I think, I like the the new behavior and would be surprised if anyone relied on getting an empty result for `maximum`/`minimum`.","created_at":"2015-08-31T20:54:07Z","updated_at":"2016-04-15T16:52:45Z","closed_at":"2016-04-15T16:52:45Z","merged_at":null,"merge_commit_sha":"bd4f2dacf95c38eb325989fa46d388f495b743e5","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/JuliaLang/julia/pulls/12893/commits","review_comments_url":"https://api.github.com/repos/JuliaLang/julia/pulls/12893/comments","review_comment_url":"https://api.github.com/repos/JuliaLang/julia/pulls/comments{/number}","comments_url":"https://api.github.com/repos/JuliaLang/julia/issues/12893/comments","statuses_url":"https://api.github.com/repos/JuliaLang/julia/statuses/22dd85c39be21983216aff72f44be57426a52d12","head":{"label":"JuliaLang:anj/tr","ref":"anj/tr","sha":"22dd85c39be21983216aff72f44be57426a52d12","user":{"login":"JuliaLang","id":743164,"avatar_url":"https://avatars.githubusercontent.com/u/743164?v=3","gravatar_id":"","url":"https://api.github.com/users/JuliaLang","html_url":"https://github.com/JuliaLang","followers_url":"https://api.github.com/users/JuliaLang/followers","following_url":"https://api.github.com/users/JuliaLang/following{/other_user}","gists_url":"https://api.github.com/users/JuliaLang/gists{/gist_id}","starred_url":"https://api.github.com/users/JuliaLang/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/JuliaLang/subscriptions","organizations_url":"https://api.github.com/users/JuliaLang/orgs","repos_url":"https://api.github.com/users/JuliaLang/repos","events_url":"https://api.github.com/users/JuliaLang/events{/privacy}","received_events_url":"https://api.github.com/users/JuliaLang/received_events","type":"Organization","site_admin":false},"repo":{"id":1644196,"name":"julia","full_name":"JuliaLang/julia","owner":{"login":"JuliaLang","id":743164,"avatar_url":"https://avatars.githubusercontent.com/u/743164?v=3","gravatar_id":"","url":"https://api.github.com/users/JuliaLang","html_url":"https://github.com/JuliaLang","followers_url":"https://api.github.com/users/JuliaLang/followers","following_url":"https://api.github.com/users/JuliaLang/following{/other_user}","gists_url":"https://api.github.com/users/JuliaLang/gists{/gist_id}","starred_url":"https://api.github.com/users/JuliaLang/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/JuliaLang/subscriptions","organizations_url":"https://api.github.com/users/JuliaLang/orgs","repos_url":"https://api.github.com/users/JuliaLang/repos","events_url":"https://api.github.com/users/JuliaLang/events{/privacy}","received_events_url":"https://api.github.com/users/JuliaLang/received_events","type":"Organization","site_admin":false},"private":false,"html_url":"https://github.com/JuliaLang/julia","description":"The
