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

Interesting never the less. Thanks, Aaron

Take a look at the record field disambiguation [1] extension to GHC. It sounds like what you're looking for. -deech [1] http://www.haskell.org/ghc/docs/6.12.2/html/users_guide/syntax-extns.html#di...

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

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.

Okay looks like name mangling with the datatypes name is in order then. Something like :- data Test = Test { testName :: String, testValue :: Int } Thanks, Aaron --

Is there any way round this ?
