Fedora Core 4 Linux, I compile this:

import std.stream;

void main()
{
         char[] c = "Saatana perkele"c;
        wchar[] w = "Saatana perkele"w;
        dchar[] d = "Saatana perkele"d;

        File of1 = new File;
        File of2 = new File;
        File of3 = new File;

        of1.create("/tmp/1.txt");
        of2.create("/tmp/2.txt");
        of3.create("/tmp/3.txt");

        of1.write(c);
        of1.write(w);
        of1.write(d);  // error line 19

        of2.write(w);
        of2.write(d);  // error line 22
        of2.write(c);

        of3.write(d);  // error line 25
        of3.write(c);
        of3.write(w);

        of1.close();
        of2.close();
        of3.close();
}

And I get the following compiler errors:

 $ dmd outtest2.d

outtest2.d(19): function std.stream.Stream.write (ubyte[])
                does not match argument types (dchar[])
outtest2.d(19): cannot implicitly convert expression (d)
                of type dchar[] to wchar[]
outtest2.d(22): function std.stream.Stream.write (ubyte[])
                does not match argument types (dchar[])
outtest2.d(22): cannot implicitly convert expression (d)
                of type dchar[] to wchar[]

outtest2.d(25): cannot implicitly convert expression (d)
                of type dchar[] to wchar[]

I would have expected complaints about maybe d and w, but not about d only. (And I would have wished no complaints at all, but that's not reasonable yet.)

It appears there is no overload for dchar[] in std.stream, I see:

  // writes a string, together with its length
  void write(char[] s) {
    write(s.length);
    writeString(s);
  }

  // writes a Unicode string, together with its length
  void write(wchar[] s) {
    write(s.length);
    writeStringW(s);
  }

but no write method for dchar[].

There is no writeStringD or writeLineD either.
