Is it just me or does this bit in the proposal: m .lookup key .snd .reverse Which translates to this: reverse . snd . (\m -> lookup m key) $ m make no sense and refuse to type check - i.e lookup is producing a Maybe not a pair for second? I can see some benefit with TDNR for record selection as per Neil Brown's message, but I have serious doubts about the syntax and find most of the examples in proposal determinedly non-compelling.
