Title: qualified modifier may reference an enclosing object

The language specification describes in section 5.2. It states that a modifier can be qualified with an identifier C denoting a class or package. However, C may also denote an enclosing object.
Example:
scala> object Enclosing {
| private[Enclosing] val qualifiedVal = 1
| }
defined object Enclosing
