I completely agreed with your original point. The fact that we went from your comment to people actually bitching about join made me really sad. I shouldn't have said that the join argument was "purely aesthetic", I should have said that it was "purely aesthetic and trivial", because you're right, aesthetics are important, and (imo) are reason enough to disallow multiline lambdas. How do you cross the line from trivial to not? I don't know exactly, but I do know that swapping the position of the involved nouns and taking up the same number of characters for a good technical reason doesn't.
