Aside: A more accurate description of that function would be cat11ret3.

A no-template version:

 int[] mul11ret3(ref int[] s) {
    s ~= 11;
    return [3];
 }

 int[] test(int[] val) {
    (val ~= mul11ret3(val)) ~= 7;
    return val;
 }

 void main() {
    static assert(test([2]) == [2, 11, 3, 7]);
    assert(test([2]) == [2, 11, 3, 7]);
 }

And a minimal test case:

 int[] mul11ret3(ref int[] s);

 void test(int[] val) {
    (val ~= mul11ret3(val)) ~= 7;
 }
