I believe what you want to do is not possible. You can certainly
create your own list type - but you can't have the interpreter create
instances of that when you write [x1,x2,x3].

What you *can* do is to create a constructor function in your module,
so you can write mymod.list([x1,x2,x3]) which should copy the
references from the argument list into your list object.
