nodes(10, 20) (30, 40) (50, 60)(do_with_nodes_so_far);

I am sure You will be very interested in this too :

Yeah, this is interesting concept, thanks for research. In the functional programming it’s called a self-reproducible or self-replicative function (if interested, I mention it in closures article — http://dmitrysoshnikov.com/ecmascript/chapter-6-closures/#definitions).

Another interesting application of such self-replicative function can be e.g. declarative form of registering some data. E.g. instead of having (semantically) two functions:

function defineNode(node) {
  ...
}

and

function defineNodes(nodes) {
  // nodes is an array
  for (...) {
    defineNode(nodes[k]);
  }
}

// single
defineNode([10, 20]);

// multiple
definedNodes([
  [30, 40],
  [50, 60],
  // etc.
])

It can one self-replicative and declarative nodes function. So, we just declare nodes:

nodes
  (10, 20)
  (30, 40)
  (50, 60);

Of course, it’s less effective than passing an array, but, repeat — just an interesting an d maybe elegant approach (I saw it before in c.l.javascript group).

However, didn’t use in on practice myself yet.
