I think he's saying that the ctor (inputting data) will use ArrayBufferView
only, but FileReader (*outputting* data) returns an ArrayBuffer, like XHR's
arraybuffer response entity body.

I wish typed arrays could be fixed so ArrayBuffer is itself an
ArrayBufferView, to fix this inconsistency, but I think there are one or
two places in the API where it would break compat...
