In my post I have not shown examples of the casts for the this 
"unsorted" category. They are sometimes needed to work around 
compiler bugs, like this one (the code doesn't compile if you 
remove the cast):

void main() {
     enum E { a, b }
     int[E][E] foo =
         cast()[E.a: [E.a: 1, E.b: 2],
                E.b: [E.a: 3, E.b: 4]];
}
