[Haskell-beginners] Can fields in a record be optional?

[Antoine Latter]

I would expect I would run into trouble with this approach - when a function
receives one of these records as an argument, how does it know if it is safe
to acces the record fields in question?

I would prefer using Maybe types, different types altogether for summed
contracts, or imaking a Contract a type with two cases (as suggested
earlier).
