A directory contains "entries" (not children). A $directory->list()
could return these children. Unless you ask for the type, mtime, or
such (hidden stat) it should stay abstract for reasons of performance.
On the other hand, you are also not allowed to cache the knowledge
without regular verification, because facts may change.
The designed interface should focus on what you want to do with the
OS, on (as abstract as possible) actions.
