I would instead make a version of this function (say, feature_err) that returns the err instead of calling err.emit(), and have this function just do feature_err(...).emit(). Then the existing callers of this function don't need to change for the None argument, and the stmt_expr_attributes one can do let err = feature_err(...); err.help(...); err.emit();.

I would say something like
`///` is for documentation comments. For a plain comment, use `//`.

Won't this help trigger for all misplaced attributes? It should only trigger for misplaced doc attributes.

Oh, I forgot to bring this up again.
This help should only be generated for misplaced doc comments, but this will generate it for any misplaced attributes at all.

@solson - sounds like an interesting point. @GuillaumeGomez ?

Didn't think of testing in other cases. Good point! I'll check a bit later.
