Wake up! dirEntries produce a lazy _range_ and it's not opApply

Sorry? Change DirIterator in std.file to this:

Yeah recent change allowed to use straight alias this in DirEntry struct 
thus there is no need for separate opApply now.

test.d:
import std.file;

bool isEmptyDir(string path)
{
     foreach (string name; dirEntries(path, SpanMode.shallow))
         return false;

     return true;
}

void main()
{
     isEmptyDir(".");
}

$ rdmd test.d
we're in oppapply
