So, in your example:
int product(const ref int[] arr) {
import std.array: array;
import std.algorithm: reduce;
arr = arr.reduce!((p, i) => p*i).array;
}
A good post overall but you got reduce wrong. In D, reduce
computes and returns the result immediately, not a lazy range.
The following code is correct:
int product(const ref int[] arr) {
import std.array: array;
import std.algorithm: reduce;
return arr.reduce!((p, i) => p*i)();
}

Damn, I was certain it acted as the two others of the trio... I
stand corrected thanks :-)
