Thank you!

This type of metaprogramming is definitely more difficult than 4Kyu.

Very clever. Brilliant use of c++

This is a very interesting algorithm, do you care to explain how it works conceptually?

Jithrae's explanation makes it sound much more complex than it is. You're simply iterating through the possible actions for each command until you reach one that receives a 'true' reply, then returning that action every time the command is called. Its really not reinforcement learning.

This Kata is intriguing, but needs a better description + test cases + failure descriptions. It's a fairly simple exercise masked as a complex one, where we're coding in the dark trying to understand what is being asked of us.

I like your implementation of instantiating card rank.

Thank you!

Very elegant

Simple and readable, true best practice and much better than most of the 'Best Practices' answers.
