In my case I’d go for embedded Lua with all the business logic in Lua and all the infra code in the host language (Go, Rust, etc…) What I have found with this approach is that sometimes it can be difficult to draw a clear line between business logic code and infrastructure code. Traversing through a list of customers to make a report… do you call a dedicated function or do it on the scripting language? If you need a slightly different report format (including address + phone number) do you write a new function on the host lang or implement it as business logic?
