std.algorithm.reduce on an array of structs

[bearophile via Digitalmars-d-learn]

Daniel Kozak:

You can just use min:

import std.stdio, std.algorithm;

struct Thing {
     uint x;
     alias x this;
}

alias minimum = reduce!min;

void main() {
	immutable ar1 = [10, 20, 30, 40, 50];
	ar1.minimum.writeln;

	immutable ar2 = [Thing(10), Thing(20), Thing(40)];
	ar2.minimum.writeln;
}

Bye,
