Comment (by goldfire):

 Parentheses are always required around kind annotations. This has been
 reported in the last six months, but, sadly, a few minutes of searching
 has not found the ticket number.

 I believe this would just require a careful look at the parser -- there
 may not be a fundamental reason for the restriction.
