Description

The following code:

class Foo {
  @Bar({ sleep 1 })
  def baz() {}
}

gives this error:

unexpected token: @ at line: 2, column: 3

The error goes away when the argument in enclosed in parens:

class Foo {
  @Bar({ sleep(1) })
  def baz() {}
}

Any other code changes (like adding explicit closure params) don't help. Class-level annotations don't have this problem. Anyone got an idea what's causing this?
