[Haskell-cafe] generalize RecordPuns and RecordWildCards to work with qualified names?

Record punning is not all that useful with qualified module names. If I write '(M.Record { M.rec_x })' it says " Qualified variable in pattern" and if I write '(M.Record { rec_x })' it says 'Not in scope: `rec_x''. Could it be this extension be further extended slightly so that 'f (M.Record { M.rec_x })' will desugar to 'f (M.Record { M.rec_x = rec_x })'? Similarly, RecordWildCards could support this too. It seems simple and useful to me... am I missing anything fatally problematic about this? Would anyone else use it?
