If you call dir without any parameters, the special directories "." and ".." are not returned, as mentioned on this page.  But if you pass a test parameter, those directories are eligible to be returned.  For example, dir(:test(/./)) returns ".".IO and "..".IO among its results.

Afaik it is intended behaviour, as they are specifically being added in the case of the "test" argument.
