Weird error when wrongly defining doc at end of struct

[est31]

Consider this code:

struct FunStruct {
    /// fun having errors
}

It is obviously wrong, doc comments have to be before items. The error rustc gives one is very weird however:

<anon>:3:1: 3:2 error: expected ident
<anon>:3 }
         ^

Is rust python?

Note this only seems to happen for structs. functions and traits display smarter error messages.

cc @nikomatsakis bc I've heard on irc he wants to be notified on weird errors.

Documentation comments expect to have something to document. You want //.

This is a duplicate of #27429.

Ah ident as in identifier, not indentation. Well then its not much worse than 27429.
