Overview of features in Clojure coming from other languages than CL

Question

I am searching for an overview of the features of Clojure that are coming from other languages than Common Lisp.

For example:

• STM: language X, Y and Z

Your input is welcome!

Answer 1

You might want to have a look at this list of books, that influenced Clojure's design, compiled by Rich Hickey himself. Looking at the titles you'll probably figure out where more of the ideas originated.

Answer 2

Some features loosely based on other languages that I am aware of:

• Lazy evaluation / lazy lists : Haskell
• Persistent data structures : Haskell and other pure functional languages
• Dynamic typing: any dynamic language e.g. Groovy, Javascript
• Type hinting (for performance): various languages
• Code-is-data and macro based meta-programming: LISP
• JVM execution and interoperability: Groovy, Scala

Ideas in Clojure that I believe are pretty original:

• Clojure-style concurrent programming with STM
• Clojure protocols (somewhat like interfaces but more powerful)

Answer 3

STM in clojure is coming from hard research in concurrency and transaction field and have implementations in Haskell(Glasgow Compiler) and more recently Fortress( High Performance Numeric Computation Language by Sun)
