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
