I am, but I read it many years ago, so I might not be able to help
In this video[0] Van Roy claims that the function Three "resolves" to 3. It's at around 8:45 minute. I tried working that out, but can't seem to get it correct. What I tried
{Inc {Inc {Inc Zero}}}
{Inc {Inc 1}}
{Inc {1} + 1}
{{{1} + 1} + 1}
Can we consider {{{1} + 1} + 1} to be 3 or what are my mistakes? Thanks.
If someone else is familiar with Oz/Van Roy stuff, I have a question.
