Hints
1. Create an empty list
Creating an empty list is just like creating a list with items. It can be done using list or using quote on an empty list.
2. Add a new language to the list
Clojure has a core function that can prepend an item to a list.
3. Check the language last added
Like other Lisps, Clojure has a function that returns the first item from a list.
4. Remove the first language from the list
Likewise, Clojure also has a function for returning a list with the first item removed.
5. Count the languages in the list
The number of items in a list can easily be returned using a Clojure core function.
6. Put it all together
Remember that function calls can be nested.
