If dir accepted a filter parameter (a predicate function) then it would be easier to filter out specific file types (e.g. files with a mode of 'file', files created in the last N days) without having to resort to additional nesting within the generic for.
(One particularly notable use of such a feature would be to filter out '..' and '.' as they often aren't relevant.)
