I don’t think you’re too far off with ‘leaving the space of normal C’, but I think it may help to see the context from which the author was coming when writing Cello [1] and evaluating it in that context.

It’s been a while since I watched the talk but I believe his intention was to do just that, to push the bounds of what could be done in a header file purely for the fun of it. The second half of the talk specifically addresses the “why are you doing this?” in quite a charming way.
