```d
template Model(T, T n = 100) // where n: length with Type of T
{
     auto voidStackArr(inout bool _void = true)
     {
         T[n] arr = void;
         assert(!_void);
         arr = 0;
         return arr;
     }
}

alias voidStackArrInt = Model!int;
void main()
{
     import std.stdio: writeln;

     // err we are reading garb values
     auto arr = voidStackArrInt.voidStackArr;
     arr.writeln;

     // ok
     auto arr2 = voidStackArrInt.voidStackArr(false);
     arr2.writeln;
}
```
and we're back to c++ u guys should really stop doing things like 
this
