This post probably just indicates that I am missing some key bits of knowledge. Why are all metalanguage classical (at least the ones I’ve seen)? Are there not any non-classical ones? Are there reasons for not using a non-classical metalanguage or there not being any, apart from making things more complicated? Surely there are discussions of these things somewhere…

On a different note, googling {{“non-classical metalanguage”}} yields 5 results. After this post it will probably yield 6.
