This is the commit where I admit that having more than one input/output format for readers and writers was complicating the code too much for a very small gain, and that it would be easier to only have one way to do it. So such way is now: - Returning (or yielding) a dict if you have key-value type collections. - Returning (or yielding) a tuple if you have a list-type collection. - Returning (or yielding) something else otherwise, which will continue to work like the old "arg0" format. IOFORMAT options has been removed in favour of a RemovedOption, which will complain if you're still trying to set it to anything else than the one value allowed.
