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

[Markus Läll]

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.
