      I don't think record field disambiguation what you're after. My apologies.

Take a look at the record field disambiguation [1] extension to GHC.
It sounds like what you're looking for.

Given a Haskell "record type" :-
    data Test
        = Test {
            name :: String,
            value :: Int
        }
    test = Test {
            name = "test",
    value = 1
        }
    main :: IO ()
    main = do
        putStrLn (name test)
Are "name" and "value" in the global name space, as the following gives an
error "Multiple declarations of `name'" :-
    name :: String -> String
    name s = s
Is there any way round this ?
Many thanks in advance,
Aaron
