You can traverse to objects in TALES that you can't traverse to in
URLs. We might be looking up an item in a dictionary. Lets say I'm
iterating over the keys in some dictionary and want to display
a value. I wouldn't want the meaning of the path expression to change just
because the key happened to contain some magic character.
