Thanks, will do.

It might be better to use std.variant.Algebraic. An array of 
tuples is wasteful of memory as you only need one or the other.

import std.variant;

alias IntOrStr = Algebraic!(int, string);

IntOrStr[] makeIntOrStrArray(T...)(T vals)
{
        import std.algorithm;
        import std.array;
        
        auto result = new IntOrStr[](T.length);
        foreach (i, val; vals)
        {
                result[i] = IntOrStr(val);
        }
        
        return result;
}

void main()
{
        IntOrStr[] arr = makeIntOrStrArray(4, "five");
}
