You're probably looking for static if:

Hello.
I'm starting to use D, and therefore Dub.
I didn't find a more suitable category than this one in the forum
to ask my question, I'm sorry if it is not the most suitable.
My concern is thus the following: I can't add packages to my
project, Dub warns me that they are not available.

In my efforts to learn D I am writing some code to read files in
different UTF encodings with the aim of having them end up as
UTF-8 internally. As a start I have the following code:
import std.stdio;
import std.file;
void main(string[] args)
{
if (args.length == 2)
{

That is more for using the frontend, not the backend for generating code.
But it's pretty advanced... probably just invoking dmd would be good...

It is very easy too... just write an ordinary function:

size_t max = 0;
foreach(t; T)

I haven't tested this specifically, but similar tests have come
in at like 1/10th the memory and compile time cost.
