because the two are not the same. When you print MyStruct to

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`, ")");
  }

Thanks. But the question was not about how to print it to 
console, but whether there are any hidden dangers in using 
Appender in this way, like the one Rene mentioned.
