In the first part [https://codecoupled.org/2015/10/18/stack-machine-part-1] we built a very basic stack-based machine and we introduced the concept of subroutines in the second part [https://codecoupled.org/2015/10/20/stack-machine-part-2]. Halt and catch fire Granting the name to a highly enjoyable TV series [https:

In the previous part of this series [https://codecoupled.org/2015/10/18/stack-machine-part-1], we looked at implementing a very basic stack-based virtual machine [https://en.wikipedia.org/wiki/Stack_machine] in Elixir [http://elixir-lang.org] . At the end of it we began to ponder the concept of functions. But

During my ElixirConf talk [http://confreaks.tv/videos/elixirconf2015-virtually-instructional] I compared and contrasted register-based virtual machines [https://en.wikipedia.org/wiki/Register_machine], like the BEAM, to stack-based virtual machines [https://en.wikipedia.org/wiki/Stack_machine], like the JVM [https://en.wikipedia.org/wiki/Java_virtual_machine]. In doing
