As you can see the output should be 1000, but it is 1.



I was a little confused by what you meant, but the following 
main is a little more obvious to me

void main()
{
        auto c = front();
        c[0] = 1000;
        import std.stdio;
        writeln(c[0]); //prints 1000
        writeln(a[0]); //prints 1
}

c is value. You can modify it with tuples. Tuples can be returned.

This thread is about mutiple values returned by _reference_. 
Tuples can not do it, only pointers, but they are not ctfeable 
and safe
