[Edit] This is actually an open question, please wait for resolution of cf. dart-lang/language#1802.

Said test contains the expression List<int>.toString(), and expects it to be an invocation of the toString method on the Type instance denoted by List<int>. However, this section specifies that it must be considered to denote a constructor invocation, and hence it is a compile-time error because there is no constructor named List.toString.

The fix could be to use (List<int>).toString(), which seems to fit the intentions of the test.
