declare var FormData: {
    prototype: FormData;
    new(): FormData;
}

in W3C
http://www.w3.org/TR/XMLHttpRequest2/#interface-formdata

[Constructor,
 Constructor(HTMLFormElement form)]
interface FormData {
  void append(DOMString name, Blob value, optional DOMString filename);
  void append(DOMString name, DOMString value);
};

in TypeScript 1.0.1 (I think this is valid!
https://typescript.codeplex.com/SourceControl/latest#typings/lib.d.ts

declare var FormData: {
    prototype: FormData;
    new (form?: HTMLFormElement): FormData;
}

These files are auto generated from the IE DOM specification. hand editing it causes things to be dropped like FormData. I would rather keep it auto generated, and get this fixed with IE's next update.

IE supports this parameter already (see network activity here http://jsfiddle.net/2aXLs/) and this constructor is used in the wild https://developer.mozilla.org/en-US/docs/Web/Guide/Using_FormData_Objects

Seems like the IE DOM spec might off here; we shouldn't just propagate that error.

👍 Agreed

this problem can't solved user land. this issue broken my real project.
If this problem will close without fix, we need #182.
