Treat class field as special function (such as `type`)

In Factorio, all the API classes have a object_name field (not function!), which identifies their class name, much like type() does for base types. We're currently handling this with a plugin that rewrites this from obj.object_name to look like __object_name(obj) which is then tagged as "Lua.runtime.special": { "__object_name": "type" }, , to get it to work properly in type-tests, but it would be nice to be able to indicate that a class field "acts like type" in this way directly.

Bắt đầu bằng cách xem xét plugin rewrite hiện có từ obj.object_name thành __object_name(obj) và ánh xạ Lua.runtime.special sang type. Theo dõi cách các type-tests sử dụng ánh xạ đó, sau đó xác minh rằng việc khai báo trực tiếp trường của class vẫn giữ nguyên hành vi mà không cần rewrite.
