Why Should a Unix Shell Have Objects?

November's release notes mentioned that YSH now has objects, using plain data over pipes like JSON or TSV, with seven use cases explained. Notably, methods, flag parsing, modules, polymorphism, pure functions, and pure config are being utilized, with YSH objects being a minimal mechanism for polymorphism and namespace creation. Additionally, objects like ENV are being used as a linked list stack, focusing on safety and access control.
