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.

It really depends on the engine, whether it's compiled (and also the compiler in that case).
Not only is it more readable, it increases efficiency. The other regex (for an arbitrary string of 16 characters) ran 114 steps, this one ran 72. Nice work.
