I'm pretty sure everyone will consider that more readable.
You've raised an issue I've wondered about as I've looked at some of the Twisted source. There seems to be a fondness for returning large expressions, rather than building up a return value in a more piecemeal (and more easily read and understood) fashion. Is this simply a matter of style, or is there something substantial going on here related to the nature of Twisted? My own code tends to look more like your second example.
My code as well, favoring more, shorter lines for clarity. I suspect the Twisted wizards don't even have to think about deferreds anymore, they just flow directly from mind to keyboard... : ) Jason
