The various implementations weren t silliness and unrelated nonsense but I presume they are off topic here and they are too much original content even in a dedicated page I think most of the code present in Wikipedia is original content The original purpose of Knuth was to design a little test to tell adult languages apart from more primitive ones but showing a list of actual adult languages and why they are adult seems off topic here The implementations are now moved by someone else here a wiki that has right the purpose of showing alternative implementations of the same code
