Rails core - Mar 2013 - Should to_io be added to ActionDispatch::Http::UploadedFile?

In
rest-client/rest-client#144<https://github.com/rest-client/rest-client/issues/144#issuecomment-14876580>
we''re
trying to handle objects that behave like IO. Some have suggested that 
respond_to?(:read) is a poor test of this and have suggested using 
IO.try_covert(obj) instead. My counter example for this is 
ActionDispatch::Http::UploadedFile. I''m wondering if there would be any
support for adding this method? I''d be happy to craft a pull request.

See: http://www.ruby-doc.org/core-2.0/IO.html#method-c-try_convert
