Talk:Self-referential function

Problems with this article

I have several problems with this article:

The definition "A self-referential function is a function that applies to itself" is hopeless. What does it mean ? How does any function "apply to itself" ??
The reference that, I assume, is intended to demonstrate the usage and notability of the term gives a "Not found" error when I try to access it.
The example from Cantor's diagonal argument that is meant to illustrate a self-referential function is clearly not self-referential ! The function g is not defined in terms of itself; it is defined in terms of the functions f_k. And the whole point of the argument is to show that g is not in the set {f_k}.
We already have a much better article at self-reference.

Unless someone can fix the definition and the example and provide some useful sources, I will seriously consider taking this article to AfD. Gandalf61 (talk) 15:51, 24 June 2009 (UTC)[reply]
