I don't like concatenating `String`s with `plus`, but at the same time it is perfectly sound mathematically speaking. If we're able to make it a `MonadPlus` and use `concat`, that would be better (but it has to satisfy the laws)."},"comment":{"url":"https://api.github.com/repos/boostorg/hana/issues/comments/196891729","html_url":"https://github.com/boostorg/hana/issues/117#issuecomment-196891729","issue_url":"https://api.github.com/repos/boostorg/hana/issues/117","id":196891729,"user":{"login":"ricejasonf","id":2257044,"avatar_url":"https://avatars.githubusercontent.com/u/2257044?v=3","gravatar_id":"","url":"https://api.github.com/users/ricejasonf","html_url":"https://github.com/ricejasonf","followers_url":"https://api.github.com/users/ricejasonf/followers","following_url":"https://api.github.com/users/ricejasonf/following{/other_user}","gists_url":"https://api.github.com/users/ricejasonf/gists{/gist_id}","starred_url":"https://api.github.com/users/ricejasonf/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ricejasonf/subscriptions","organizations_url":"https://api.github.com/users/ricejasonf/orgs","repos_url":"https://api.github.com/users/ricejasonf/repos","events_url":"https://api.github.com/users/ricejasonf/events{/privacy}","received_events_url":"https://api.github.com/users/ricejasonf/received_events","type":"User","site_admin":false},"created_at":"2016-03-15T15:52:22Z","updated_at":"2016-03-15T15:52:22Z","body":"We could make a new concept `IntegralSequence<T>`, add impls for all functions for concepts that `Sequence` refines and add it in the concept checks for each of those functions.
