Hello everyone, I have just started studying Haskell and I am having a hard time understanding type and value constructors. So to create a new type, you write something like: data FinancialInstrument = Financial String Double deriving (Eq, Show) and then you can write: ibm = Financial "ibm" 150 OK all good. This initializes a FinancialInstrument. What I don't quite grasp is what is the purpose of Financial (the data/value constructor)? And from what I have read, you could have also written: data FinancialInstrument = FinancialInstrument String Double deriving (Eq, Show) To me the second expression is a lot closer to the typical OOP way of doing things (where the type name and constructor(s) have the same name). Why would someone prefer the first notation? Once a value has been constructed, how can I access its fields? Is there a way to create values using named parameters? Thanks!
