class A { int m=5; }

int main()
{
    A[] a=new A[1];
    immutable(A)[] b=[new immutable(A)];
    assert(b[0].m==5);

Interesting...

class A { int m=5; }

int main()
{
    A[] a=new A[1];
    int[] b=[0];
    a[]=b[];
    return 0;
}

this code gives error: cannot implicitly convert expression (b[]) of type int[]
to const(A[]). Seems like the compiler tries to cast right-hand expression to
const(typeof(left-hand expression)), then proceeds with copying.
