That API is reasonable, if you have a patch, I would accept it (preferably including full test coverage).
Another thing that was talked about for a while is our intention to have req.FILES or similar which would include just the file uploads. So setting it / passing it to .blank(..) would accomplish the same thing. I don't have time to implement it for now, so it's hard to tell when it will be available.
Ok, you got me. That was second issue I wanted to report. We have an implementation of separate `FILES` attribute in `Request` class, but no tests for now. And no confidence of normality =)
