As for the example, you can rewrite it like so:
----
auto failhard(T)(T iter) {
    import std.stdio;
    import std.range: take, drop, refRange;

    writeln("We have some range:");
    writeln(typeid(T));
    writeln("We take 1 from it...");
    writeln(refRange(&iter).take(1));
    writeln("The rest of the range has:");
    writeln(iter);
    writeln("");
}

Also need to add @property to `front` and `empty` in the ranges.
refRange is picky about this.

My apologies, that actually prints "[0, 1, 2, 3]" in the array case. I 
don't what's going on. That should work. Maybe I'm misunderstanding 
something about refRange.
