The sizeof values aren't relevant for D array casts. What
matters are the array contents.
See:
void main() {
int[5] m = cast(int[5])[1, 2, 3, 4, 5];
assert(m == [1, 2, 3, 4, 5]);
pragma(msg, m.sizeof); // 20u
pragma(msg, [1, 2, 3, 4, 5].sizeof); // 8u
}

Baz:
int[3] m = cast(int[3])[1, 2, 3];
writeln(m.sizeof);
writeln([1, 2, 3].sizeof);

Currently this is accepted:
int[2] m = cast(int[2])[1, 2];
But Kenji suggests that the cast from int[] to int[2][1] should
not be accepted. Do you know why?
