- Instead of having to pass context data between the
recursive function calls, create an type/object to hold
this context data, which also contains the flattening
functionality itself.
- Allow the flattening functions to be more easily
extended by having a selection function that matches
item type to flattening function.
- Add pre/post flattening functions (which can be
extended/inherited to do different activites as
needed).
