      @propensive Yep! Who doesn’t want their cast to be determined by type inference?

      @djspiewak @propensive WTF!? And I thought I knew all the dark corners already... Does it always infer Nothing?

      @djspiewak @oxnrtr It's particularly useful when you know the complex part of the type will go away with erasure anyway.

      @pedrofurla @propensive @djspiewak @oxnrtr can't find an example where the compiler doesn't infer Nothing, e.g. https://gist.github.com/SethTisue/6444477 …

      @SethTisue @pedrofurla @djspiewak @oxnrtr Though it was in macro code, so that's never going to fit in a tweet...
