Re: [Haskell-cafe] "record" types and unique names

30 Dec 2010

      Yes, they are in the global scope, and from what I gather: they are just
regular functions, created by special syntax.

There are a few obvious solutions (some of which you might have thought
yourself :-):
 - rename the accessor or the other function, or
 - put the data declaration or the other function in another module and
import qualified, or
 - write a typeclass with a 'name' function and fit the non-accessor
function 'name' somehow into that...

I think the best approach is the modular one, but this really depends on
what you are doing.

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,
