      Description

      Consider the following:

      @groovy.transform.TypeChecked
      void test() {
        List<String> a = [] // okay
        Set<String> b = [] // okay
        Deque<String> c = [] // GroovyCastException at runtime
        Deque<String> d = [1,2,3] // error for unknown constructor (interfaces don't have them) and error for incompatible generics
        ArrayDeque<String> e = [123] // ArrayDeque(int numElements); error for incompatible generics (bad)
        Set<String> f = ['foo', 'bar', 'foo'] // error for unknown constructor (castToType would handle this at runtime if allowed) and error for incompatible generic types (wrong)
      }
