!til &virtual-machine In addition to register based machines, which provide memory and dedicated registers, there exists stack based machines which only provide memory and a stack pointer (typically at the end of memory) that is decremented when new values are pushed onto it. Register machines are arguably harder to construct, but produce faster results that can be optimized, whereas stack machines require fewer instructions and are simpler to implement, but are a lot slower. An example of a good stack VM that's so simple it's commonly programmed in it's assembly language is https://wiki.xxiivv.com/site/uxn.html

uxn has the design closest to what I'm looking for, but I'll talk more about that next week
