I love that example of the lua error message, but aren't there non-arithmetic functions that also error? What's the message in that case? What's nice about Python's message is how compositional or "orthogonal" it is, which means that the errors can easily be handled in a program. Does Lua have anything like that? From the manual > If you need to handle errors in Lua, you should use the pcall function (protected call) to encapsulate your code. This actually helps me understand a bit the dichotomy between "configuration" and "program", and why Lua is so good for the former. As another comment put it, it's good when you need to "describe stuff". It doesn't make a lot of sense to describe something that handles errors in its own description, which motivates relegating error handling to specific contexts.
