The code in Ex.1 compiles and runs fine but I think it needs a cast:
---
// Ex.1
void main()
{
    int[] a=[1,2,3,4];
    int[2][2] b = a;
}
---


Array assignment in Ex.2 only works with a cast:
---
// Ex.2
void main()
{
    int[] a=[1,2,3,4];
    int[2][2] b;

    b = a; // Compile time error

    cast(int[4])b = a; // works ok
}
---

I think it should be consistent, preferably with a cast.


Thanks,
ed
