It was a pleasant surprise how easy it was to add. Serious thanks to @mbauman for providing the hint to get this functionality that an outsider like me would otherwise have no idea about.\r\n\r\nSpeaking of being an outsider, I tried to be as non-controversial as possible, by just replicating the current `*` concat method and not allowing any other generic use. I was motivated to make this PR because I really liked the idea of a generic sequence concat operator but others can work out the details for that.\r\n\r\nThis will break code if anyone was doing something like `x++1` (as `x + (+1)`) which is pretty unlikely but possible.\r\n\r\nI guess the long-term plan would be to decide if `++` should be added to 0.4, and then if so, the whole debacle of deprecating `*` would be discussed/argued/executed in 0.5-dev? I'm looking forward to watching the comments with my popcorn..."},"comment":{"url":"https://api.github.com/repos/JuliaLang/julia/issues/comments/112843117","html_url":"https://github.com/JuliaLang/julia/pull/11686#issuecomment-112843117","issue_url":"https://api.github.com/repos/JuliaLang/julia/issues/11686","id":112843117,"user":{"login":"phobon","id":3770090,"avatar_url":"https://avatars.githubusercontent.com/u/3770090?v=3","gravatar_id":"","url":"https://api.github.com/users/phobon","html_url":"https://github.com/phobon","followers_url":"https://api.github.com/users/phobon/followers","following_url":"https://api.github.com/users/phobon/following{/other_user}","gists_url":"https://api.github.com/users/phobon/gists{/gist_id}","starred_url":"https://api.github.com/users/phobon/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/phobon/subscriptions","organizations_url":"https://api.github.com/users/phobon/orgs","repos_url":"https://api.github.com/users/phobon/repos","events_url":"https://api.github.com/users/phobon/events{/privacy}","received_events_url":"https://api.github.com/users/phobon/received_events","type":"User","site_admin":false},"created_at":"2015-06-17T15:21:18Z","updated_at":"2015-06-17T15:21:18Z","body":"@ScottPJones I think those methods all look quite reasonable. However, I don't think this is the place to discuss them since that amount of logic will definitely not be in this PR, which is just about whether the `++` operator should be introduced."}}
