With dmd 2.065beta this compiles and runs with no errors:

int[2] foo() {
    int[] a = [1, 2, 3, 4];
    return a[0 .. 2]; // OK
}
void main() {}


This compies and runs with no errors:

void main() {
    int[] a = [1, 2, 3, 4];
    int[2] b;
    b[] = a[$ - 2 .. $]; // OK
}


While this code:

int[2] foo() {
    int[] a = [1, 2, 3, 4];
    return a[$ - 2 .. $]; // Error
}
void main() {}


Gives:

test.d(3): Error: cannot implicitly convert expression (a[__dollar -
2u..__dollar]) of type int[] to int[2]

I'd like this code to compile.
