well that's only natural as :+: just as unsymmetric and it's easy to exploit that fact - cudos for you if you did not use this but I think you make your life to hard this way

there are some issues with people complaining about timeouts in there code and indeed I ran into the same issue.

So I really looked around in my code and could not figure out why it should take so long (yeah it's a mess - but after that I don't want to refactor the correct monad stack anymore).

In the end it was rather simple: there seem to be input with spaces (char ' ') and in my case for some reason the resulting exception/failure ended up in CW complaining about timeouts.

So I would suggest adding some remark about this or removing invalid characters from the test input

the newer test cases forbid using functions from Data.List - so this will not work anymore

I just retried and sadly there seems to be no way to keep most of this from the user (as the Preload just don't work) - maybe you can help me out here? For now I'll close this

sadly I cannot get this to work either right now - the system is quite buggy

my first versions did hide all this in the hiden parts of the kata - but it seems that there s a major bug: it works on submit and while I develop the solution but not when users test their code - if this changes I will happily move all the exposed code back

thank you for your suggestion - will do

ok - you have to reset even if you try again to see the current changes - now it works on my site - still I had to include all the code I wanted to hide ... frustrating

the worst thing is: I changed it to not use the preload section of the code and re-uploaded it but it's not changing the code for training - this site seems to be broken badly - sorry guys.
Can someone help of shall I delete the Kata - it's really frustrating right now

yes they must have changed their Preload system - it was working on friday and now it's broken.
I have no clue how to fix it right now :(

well sorry but there is a major bug in the system right now - I republished a new version without the preload but it does not show up

should be fixed - this is a bug in the system - the preload part is not loaded

of course there were test-cases (as you've said in your second part of your comment) - just no example test cases, and I've now included a few
