I just tested the naive way:

delegate void SumLambdaType (int a);

void main () {
    SumLambdaType sum0 = (a) => { print("%d\n", a + 0); };
    SumLambdaType sum1 = (a) => { print("%d\n", a + 1); };
    SumLambdaType sum2 = (a) => { print("%d\n", a + 2); };
    SumLambdaType sum3 = (a) => { print("%d\n", a + 3); };
    SumLambdaType sum4 = (a) => { print("%d\n", a + 4); };
    SumLambdaType sum5 = (a) => { print("%d\n", a + 5); };
    SumLambdaType sum6 = (a) => { print("%d\n", a + 6); };
    SumLambdaType sum7 = (a) => { print("%d\n", a + 7); };
    SumLambdaType sum8 = (a) => { print("%d\n", a + 8); };
    SumLambdaType sum9 = (a) => { print("%d\n", a + 9); };

    sum0(42);
    sum1(42);
    sum2(42);
    sum3(42);
    sum4(42);
    sum5(42);
    sum6(42);
    sum7(42);
    sum8(42);
    sum9(42);
}

Sadly that is still fully deterministic.... It might be because multiple files? not sure yet.
