I imagine this is how one would program computers in Wonderland, if there were any. It's not meant to be particularly difficult to use, but it has a different perspective. It requires a few characters not found in the ASCII character set: I suspect keyboards in Wonderland would have a great deal more keys than ours.
Wonderlang hasn't made it onto esolangs.org (yet). To be fair, I haven't written a proper specification for it, which seems likely to be a requirement. But then that's probably another natural characteristic of programming in Wonderland - why should they need to write this stuff down, or if they did, despite needing to, why should they go and actually do it? After all, they're all mad there.
