Mal is a learning tool. See the make-a-lisp process guide. Each implementation of mal is separated into 11 incremental, self-contained (and testable) steps that demonstrate core concepts of Lisp. The last step is capable of self-hosting (running the mal implementation of mal).
The mal (make a lisp) steps are:

• step0_repl
• step1_read_print
• step2_eval
• step3_env
• step4_if_fn_do
• step5_tco
• step6_file
• step7_quote
• step8_macros
• step9_try
• stepA_mal

Mal was presented publicly for the first time in a lightning talk at Clojure West 2014 (unfortunately there is no video). See examples/clojurewest2014.mal for the presentation that was given at the conference (yes the presentation is a mal program). At Midwest.io 2015, Joel Martin gave a presentation on Mal titled "Achievement Unlocked: A Better Path to Language Learning". Video, Slides. More recently Joel gave a presentation on "Make Your Own Lisp Interpreter in 10 Incremental Steps" at LambdaConf 2016: Part 1, Part 2, Slides.

If you are interesting in creating a mal implementation (or just interested in using mal for something), please drop by the #mal channel on freenode. In addition to the make-a-lisp process guide there is also a mal/make-a-lisp FAQ where I attempt to answer some common questions."
