at the same type I don't like objects which have fields which are unused or have no meaning if a discriminant has some value, it makes debugging harder and the model harder to understand.

we'll find the right balance.

  | Same here. I tend to prefer a generic object to handle as much as possible with only minimal sub-classes as required. As far as debugging goes, toString is our friend: as long as we have enough information in the object (and we should), we should be able to have a toString method that could be leveraged while debugging.
