I think he was referring to code-rewriting rules? As for those they are
very different with respect to the domain & type of the language -
functional, imperative, object oriented, declarative languages all have
different patterns. E.g. tail call optimisation is essential in
functional languages, and more or less irrelevant in others.

I don't know of a good collection, but if anyone does, please go
ahead :-)
