He also announced another language, Seph, which was supposed to be a more production friendly version of Ioke. It looks like it might also be defunct. http://en.wikipedia.org/wiki/Seph_(programming_language)
I respect his way of openly experimenting with such things. They are a great read, if only just for inspiration.
Interestingly enough, ALGOL68 already supported localized keywords.
The problem is you need to translate all the core language, not only keywords, e.g. list map(root) fold(plus) -> elenco mappa(radice) ripiega(più).
Supporting localized keywords in a parser would be relatively straightforward and a much smaller job than translating the whole standard library in something intelligible, I believe.
