-  // the path (its "proper" representation would have been an empty

-  // around this snag, this implementation, during key comparison,
-  // detects '/' and treats it as empty. Note that the map will
-  // still store the key as you have first inserted it. So if you
-  // want a particular representation (i.e., empty or '/'), pre-
-  // populate the map with it.
