So I find myself Doing this kind of thing very frequently. I have a Array of Somethings and i want to see if "something specific" is inside the array. I wrote a template for it. but is this the best way to do this kind of thing. I feel like it doesn't help with readability. Is there a better way? Maybe i missed something in the std library.

import std.stdio;

template FNDR(T){
    bool isIn(T Element, T[] Array){
        bool rtn=false;
        foreach(T ArrayElement; Array){
            if(Element==ArrayElement){
                rtn=true;
            }
        }
    return rtn;
    }
}

void main(string[] args)
{
    int[3] stuff=[0,1,2];
    if (FNDR!int.isIn(2,stuff))
    {
        writeln("Hello World!");
    }
}


Is there a way maybe to make it look like this?

import std.stdio;

template FNDR(T){
    bool contains(T[] Array,T Element){
        bool rtn=false;
        foreach(T ArrayElement; Array){
            if(Element==ArrayElement){
                rtn=true;
            }
        }
    return rtn;
    }
}

void main(string[] args)
{
    int[3] stuff=[0,1,2];
    if (stuff.contains(2)) // Much clean! stuff.FNDR!int.contains(2) doesn't work
    {
        writeln("Hello World!");
    }
}

I'm interested in what you guys think? what is the cleanest way to do this?
