That sounds miserable. Is there blog post or something with more details that supports this? I might be having a knee jerk reaction because I can't imagine something like this being easy to work with and maintain but I recognize you were just giving a trivial example.

This was a blog example I saw a few years ago, it went through making a calculator program without using ifs. Looked pretty nice. I can't find it now though.
