<< It wouldn't be difficult to do so, it would be impossible. >>

Rather what I was implying, but as Dirk replied, if foreach was a tag
method then something could be done.

For the moment I have implemented a "special" foreachi in C for my own
table. Redefining getn() would be more problematic, as it would need to
detect whether or not it was working on a "special" table. Making getn a
tag method would answer most of this problem, but until I have become more
confident with lua I'm not about to go extending the language in such ways.
