digitalmars.D.learn - dirEntries: How get "." and ".."?

Why does dirEntries in std/file.d do that (POSIX version)?:

             for (dirent* fdata; (fdata = readdir(_stack[$-1].h)) 
!= null; )
             {
                 // Skip "." and ".."
                 if (core.stdc.string.strcmp(&fdata.d_name[0], 
".") &&
                     core.stdc.string.strcmp(&fdata.d_name[0], 
".."))
                 {
                     _cur = DirEntry(_stack[$-1].dirpath, fdata);
                     return true;
                 }
             }

There seems to be no switch to disable the skip of "."  and "..".
So the original position of these dir entries is lost. ☹

I imagine dirEntries returning an entry for ".." would make for a 
lot of confusion.

Don't you already know "." as the path you passed to dirEntries? 
What exactly are you trying to do?

IMHO the application programmer/software engineer needs no such
protection. [sarcasm deleted]

I don't know the change date, the uid/gid etc.

I am refactoring a Filebrowser.

Not as sexy, but can't you manually construct DirEntries [1] by supplying the
paths via std.path 
[2]? DirName [3] should give you the current/parent directory, for example.
