Loading collection data...
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.

Of course, I was just commenting because for me, as a mathematician, it was on the first glance confusing that this actually works :D
To be fair, the type definition is Int -> Int, not (Num a) => a -> Int, so a Double would never be allowed into the function.
Note that this definition would not work for Double, e.g. 2.25=1.5^2 would be sent to 2^2=4, because 1.5 gets rounded to 2, although 2.25 is closer to 1 than to 4.
