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.

My understanding is that there is a default test so that '.' and '..' 
are not returned. So if :test is not specified thats the behaviour you get.
