If the only reason is that nobody has written the code, this would be something I'd like to work on.
I found myself copying my code and pasting it in a repl to see what output I was getting to know my mistake. If that's on purpose because it's better to read through and think about the code rather than trial and error your way to a solution, I can understand that. If it's not intentional and just needs someone to implement it, I'll try my hand at it.
