Can we somehow go through other places where we call Enso code in the interpreter to verify that a similar bug is not hiding somewhere there?

I have grepped getCallTarget and there are no other places using this exact form. It is however still possible for other nodes to be broken like this. The only way to do it would be to go through every builtin method to see if it uses tail calls correctly. And there's a looooot of them.
