We can't wright a generic unittest to make sure that a range 
"works". Indeed, depending on *what* your range iterates, the 
test would be different.

You just have to test that yourself.

The easiest way is to give your container the "Range opSlice()" 
function, where Range is the range you defined to iterate on your 
container. See std.container.array.
