 *   - Java integration
 *   - Annotations
 *   - Tail recursion optimization
 *   - Enums
 *   - Vals vs. vars
 *   - Working with singleton objects

Array abstraction in Clojure

Few days ago Mike Anderson wrote [a proposal][mike] for a generic matrix API in Clojure which could compete with NumPy. I wanted to write a similar post for months, but was reluctant to start. This problem is very dear to me. Basically, it is a matter if I can use Clojure for most of my work, or it remains a toy language for me. Thanks to Mike for bringing the question up. Though, I have a different vision of how we should approach arrays and matrices in Clojure.
