I thought it's obvious that you can't iterate backwards if you dont have random access property or don't know length (or cant slice), and i think it's a spoiler (kind of), but i put in description, thank you.

which is not an iterator but an range object

I didnt say that Table.data is iterator. Iterator is what Table.walk() should return.

How should i test it?

Oh, i see. Added test for this. Thank you.

Interesting. Since i added more random tests and widen random range, I believe its now imposible to guess solution (eight numbers) by chance (maybe still possible by intercepting randomizer state?)

thank you

Added more random tests
Added tests for edge cases
I'm afraid dimensions of length 0 will overcomplicate this already complicated (for me) kata, [] and [[]] and [[],[]] is valid tables but need many tests to cover.
Put a note about in description.

That means that a warrior can bypass half of the problem by doing this

I dont see how this might work, any code that redefines them wont pass any of simple tests (except obviously first two tests)

get rid of DIRECTION_NONE

Thank you.
