[jdom-interest] Traversal

[Robert DiFalco]

Okay, I know this has been hashed out repeatedly but I don't quite
understand how the List interface makes using ArrayList more difficult or
require factories?!?

It also seems like if there where a single interface (or even better an
interface hierarchy using the Composite pattern) one could do typed
traversals using the Visitor pattern with out the need for cased instanceof
checks.

I don't see how this would adversely impact the use of concrete classes.
After all, I say "new ArrayList()" all the time.

Am I missing something?
