[Haskell-cafe] Domain modeling

29 Jan 2020

      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
