No, what about this:

```d
  import std.stdio;

  enum MySuperLongNameFlag : int
  {
      A = 0b0001,
      B = 0b0010,
      C = 0b0100,
      D = 0b1000,
  }

  void set_flags(MySuperLongNameFlag f) {}

  void main()
  {
     MySuperLongNameFlag flag = A | B | C | D;
     set_flags(A | B | C | D);

     writefln("%04b", flag);
  }
```

No bloat, no extra indentation, no auto, you know what you are
