Well, there are perfect hashes, and jukeboxes (or even phonographs, even though they may break).

----Response----
[orcmid] I don't understand the appeal to Gödel numbering and certainly anything in particular to do with hashing.

If it had been available at the time, the identification of the symbols that Gödel chose to "number" would work just as well with use of a Unicode encoding for those numbered glyphs and then using strings of Unicodes in the formations on which Gödel based his arguments.  They make perfectly good bignums 😊.

My main point is that Gödel numberings and, say, UTF-8 strings have equivalences and one would not use an argument about those UTF-8's as something special about hashing as far as I can discern.
