Nope, the KO rule does not prohibit multiple passes. I don't believe there is any limit on consecutive passes in this kata.

If black passes, then white passes, is that a KO Rule? Because in this situation black's position is repeating

Oops, it seems it does work. Earlier when I tried to run my code in it, the code threw an error in the declaration of main, but now it doesn't. My bad, it seems I was a bit hasty.

prove it: What's the problem? Otherwise that's not even close to an "issue" (114 completions).

Python versions don't work

You're right, my bad. You made a really good kata, it's been a lot of fun to solve it.

This fits for Expect a variable but got a list. var A B[20]\nlset B B 20
Where M4WkCHiToPUcQNaCVNzAlqZR_aIT5 [20] is a list but a variable is expected in b2a $$ $$ z4fgl0tOziOgri4AfTsI44PJY M4wkcHitoPucqnAcVNzAlQZR_aiT5

This is one of the tests. Thanks for the fast reply btw!

In the random tests. It inputs a valid code, except for the fact that it reads but the input array is empty.

it says that the transpiler should throw an error when no input was given (after a read call)

Where? in the description or the complete tests?

In the JavaScript version, it says that the transpiler should throw an error when no input was given (after a read call), but there is no way to do that since the program doesn't have access to the input.
