Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I recommend removing step 3 from the instructions. It is very confusing, and not only because of the bad English. The fact that it has its own number and associated text seems to imply that something should be done here, but nothing actually needs to be done in this step. I wasted several minutes trying to decipher this part.

Fixed (you need to reset the trainer to see the fix).
The F# version has a bug in the test that refers to the function as "friend", but the boilerplate code uses the name "friendOrFoe". I had to modify the test before I was allowed to submit.

Nice idea!
Although it's easy to deduce what you want by looking at the tests, it should be explained more clearly in the instructions what is supposed to be done with the input to create the output.
I initially just did the textbook hello world, but something made me come back and do it in a more interesting way.
How do you know if you're using functional approach? is it when you use advanced methods like composition, currying and partial application? Because from what I know, applying the principles are enough to be considered as functional (Immutability, Higher-order & first-class function, referential transparancy, etc).
If the advanced methods are not required, then you don't have to use it.
Yeah, It's kinda sad that people don't cheat not because it's not allowed, but because they can't.
