To be fair, the article would be more aptly titled "Recursion without function names". In any recursion you need a way to reference the original function somehow. They're using a function parameter to accomplish that via indirection.

There are no names except function arguments.

No 'x=...'

Please reread my post. The function parameter is the name.

Do you know a language without argument names?

You're missing the point. Nevermind.
