It seems logical to transfer such tests with additional spaces to fixed tests.
Otherwise it's possible (at least in Python) to randomly solve the kata with partial solution that does not preserve additional spaces.

Your comment doesn't make sense since I didn't speak about myself, I spoke about the kata

Fascinating! Hugely faster than my solution.
And I cannot figure out why the difference is so huge. I see some inefficiencies in my code, but eliminating them didn't make any big difference

Really strange description. Even after solving I still cannot grasp the idea what is preloaded and what is not, what objects are instantiated, at which point in time, how I was able to redefine them, etc.

Agree! Description needs an update)

I completely agree. No matter of the kata level - clear explicit requirements is the best practice.
I suppose we all here prefer to code more and spend less time on understanding the requirements)

I completely agree. It seems that task would be easier to understand if information about preloaded names would be explicitly stated in the description.
As well as others I had to go to the discussions to find out that they're preloaded.
Maybe "objects <...> are given" sounds a little bit not straightforward compared to "objects with aliases needed are already preloaded for you. The names of these objects are:<...>"

I agree that this is not an 8 kyu. In terms of code - yes, but in terms of all the formula stuff and the way task is formulated - at least 7 kyu

I totally agree that this is at least 7 kyu. Even though the solution is quite simple in the end - it could be not so easy for people at 8 kyu
