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.

I'm a bit dissapointed with this kata series. Not only they're very easy, the tests do not cover every tricky case, opening doors for some cheap cheating.

Phew. Finally got a hold of remove() method, this one was tricky to guess right.

Wow, that's not as easy as it looks.
I managed to pass all the test past this one: 'Removing 'a' from '(a)': Test Failed: l1.remove(first) is empty'.
Any hint? This seems a bit strange to me.
Can someone elaborate what's going on there? (: It's a bit complicated.
