Doc block not allowed for the last element of an enum

[Geal]

enum a { 
  B = 0, /** hello */
  C, /** world */
  D /** ! */
}

fn main() {
}

$ rustc enum.rs 
enum.rs:4:5: 4:13 error: expected `}`, found `/** ! */`
enum.rs:4   D /** ! */
              ^~~~~~~~

Not a big issue, but still a bit annoying. If I remove the last code blocks, it compiles fine.

The doc blocks have to go before the enum variants, not after them.

enum a {
  /** hello */
  B = 0,
  /** world */
  C,
  /** ! */
  D
}

Yes, this is currently expected behavior.
