I tested 3 D variants :

---ver1.d
double sum = 0.0;
for (int i = 0; i < values.length; i++)
{
	double v = values[i] * values[i];
	sum += v;
}


---ver2.d
double sum = 0.0;
foreach (v; values)
         sum += v * v;
return sum;


---ver3.d
import std.algorithm : sum;
double[] squares;
squares[] = values[] * values[];
return squares.sum;

All 3 were the exact same with LDC. https://run.dlang.io/is/6pjEud
