The following (arguably valid, arguably invalid) code compiles successfully but
produces wrong results at runtime:

void main() {
    int[2] foo = [1, 2];
    string[int[2]] aa;
    aa[foo] = "";
    assert([1, 2] in aa);  // FAILS

It should either be a compiler error (if the literal [1, 2] is treated as a
dynamic array and polymorphism between dynamic and static arrays is disallowed)
or it should work.
