The problem is that the spec is inconsistent.  In the first case, it's not an
array literal, but an array initializer.

ArrayInitializer:
        [ ]
        [ ArrayMemberInitializations ]

ArrayMemberInitializations:
        ArrayMemberInitialization
        ArrayMemberInitialization ,
        ArrayMemberInitialization , ArrayMemberInitializations

versus

ArrayLiteral:
        [ ArgumentList ]

ArgumentList:
        AssignExpression
        AssignExpression , ArgumentList


Making these consistent is technically an enhancement request rather than a
bug.  I nearly set this to enhancement, but the second issue (repetition of the
error message) qualifies as a bug IMO.
