As a Roblox developer, it is currently too hard to perform reflection on builtin classes. For example, if I want to get a list of properties of the Lighting service, I have to either manually type them out or do some shenanigans with HttpService to get an up-to-date property list. Both are incredibly tedious. Something like Instance:GetProperties() would be a nice solution, giving a list of properties that contains their property name and expected value, as well as if it’s assignable (i.e. read-only or read-write capable) and any other relevant information.
If Roblox is able to address this issue, it would improve my development experience because there are oftentimes cases where I need to cache properties for later. For example, getting a list of Lighting properties when the server starts so I can reset back to a “default” state if I ever change any of the lighting properties. Currently, I have to manually type out each property I want to cache and set it manually as well.
