I've been getting a lot of mileage from DuplicateRecordFields lately. You
just have to commit to not using labels as accessors. That is, no writing
`indMov x`. Instead, you have to write something like `myFunc C170{indMov}
= ...` (with NamedFieldPuns) or `myFunc C170{indMov=someBinder} = ...`.

Hi!
I'm trying to encode a domain which is full of simple records, and a lot of field name clashes.
Here is a simple example, a.k.a. 1:1 with the domain-spec:
data C001 {
-- other stuff indMov :: Bool } data C170 { -- other stuff indMov :: Bool }
There is ~148 records with this field (indMov), all with the same meaning. What are my options to encode this in Haskell?
- Prefix all record fields to avoid name clashes? - Use *DuplicateRecordFields*? - Typeclasses??? - other options I am not aware of?
which would you prefer? and why of course :)
Thanks, Jean Lopes
