Partly off-topic, but interesting, IMO: This thread (the word "stack") triggered a memory of stack machines, which I had read about much earlier, in computer mags such as BYTE. Looked it up just now, and saw: https://en.wikipedia.org/wiki/Stack_machine#Virtual_stack_machines https://en.wikipedia.org/wiki/Stack_machine#Virtual_stack_ma... which says that the JVM, CPython and a couple of Ruby VMs are virtual stack machines.
