I'm a bit conflicted on this. MDN says that Function.length is the number of formal parameters, and I think I would want that to be 2 for Blob and 3 for File. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Obje... What do you think? I can definitely change the expectation. The "FAIL" bothers me a bit :)
