This should do the job.  I tested that it compiles, and it's pretty hard to
have a logic error given that it's supposed to do nothing.  Just to make it
explicit, I hereby release the DummyStream class into the public domain, if
it's even copyrightable.

/**A dummy stream for disposing of output.  Supports the interface of an
 * OutputStream, simply does nothing for any method call.*/
class DummyStream : OutputStream {
    this() {}

    void writeExact(const void* buffer, size_t size){}
    size_t write(const(ubyte)[] buffer) { return buffer.length; }
    void write(byte x) {}
    void write(ubyte x) {}
    void write(short x) {}
    void write(ushort x) {}
    void write(int x) {}
    void write(uint x) {}
    void write(long x) {}
    void write(ulong x) {}
    void write(float x) {}
    void write(double x) {}
    void write(real x) {}
    void write(ifloat x) {}
    void write(idouble x) {}
    void write(ireal x) {}
    void write(cfloat x) {}
    void write(cdouble x) {}
    void write(creal x) {}
    void write(char x) {}
    void write(wchar x) {}
    void write(dchar x) {}
    void write(char[] s) {}
    void write(const(wchar)[] s) {}
    void writeLine(const(char)[] s) {}
    void writeLineW(const(wchar)[] s) {}
    void writeString(const(char)[] s) {}
    void writeStringW(const(wchar)[] s) {}
    size_t vprintf(char[] format, va_list args) { return 0; }
    size_t printf(char[] format, ...) { return 0; }
    OutputStream writef(...) { return this;}
    OutputStream writefln(...) { return this; }
    OutputStream writefx(TypeInfo[] arguments, void* argptr, int newline =
false) {
      return this;
    }
    void flush() {}
    void close() {}
    bool isOpen() { return true; }
}
