Now C++ has already 3rd version of ranges and they are still not used in general.

But since I'm a C programmer who just play with D as hobby I would need more time to digest it. I'll try to read it later. Matheus.

auto enumPrint(T)(size_t len = 0) { int[string] result; int i = 1; for(T x = T.min; x <= T.max; x++) { result[len ? x.to!string[0..len] : x.to!string] = i++; } return result; } enumPrint!DayOfWeek(3).writeln; }

Here's a challenge. Given an input year, for example, "2023", write a program that outputs (for the corresponding year):

Code will be graded on readability, unittest coverage, and reusability (how many functions have wide applicability outside of this challenge).

;-)

import std.process, std.stdio;

void main() {
	writeln(executeShell("cal -y 2023").output);
}

Don't let this go to your head :), but I was blown away by the presentation and solution! BTW where is it posted?
