because the two are not the same. When you print MyStruct to console you get the address of appender buf, whereas when you use string[] items you get the actual items. I'm only wondereing if using appender is potentially dangerous and could bite me later.

Why don't you implement "toString" on your type?

  void toString(scope void delegate(const(char)[]) sink)
  {
      import std.format;
      formattedWrite(sink, `%s`, "MyStruct(");
      formattedWrite(sink, `"%s"`, name);
      formattedWrite(sink, `%s`, ", ");
      formattedWrite(sink, `%s`, buf.data);
      formattedWrite(sink, `%s`, ")");
  }
