Despite being natural and intuitive this feature was rejected due to being a serious breaking change to poorly written yet massive code bases.\n\nPlease consider putting it behind a flag provided the evident need for it.\n\n**TLDR**\n- `any` is not what you think it is (poor naming at play)\n- for narrowing use `type unknown = {} | undefined | null | void` instead\n- yes, it's a hot unfortunate mess\n- no, there is no painless way to fix it\n- yes, you gonna need to fix your `*.d.ts` by hands\n- why? to make average JS developers happy with their less than perfect code\n- welcome to the club! get your badge at the reception\n\n**UPDATE**\n@yortus made a branch per https://github.com/Microsoft/TypeScript/issues/9999#issuecomment-238070961 where **narrowing from `any` works!**\n\ntry it: `npm install typescript-narrowany`\n","author":{"url":"https://github.com/zpdDG4gta8XKpMCd","@type":"Person","name":"zpdDG4gta8XKpMCd"},"datePublished":"2016-07-28T01:47:35.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":120},"url":"https://github.com/9999/TypeScript/issues/9999"}
