I don't think Vim 9 script needs or would gain anything for such extensions. > Context: I'm taking a stab at parsing protobuf definitions into Vim 9 > classes. Nested messages in the protobuf demands ><https://arc.net/l/quote/qfcssecm> nested structs/classes. Something like: message SearchResponse { message Result { string url = 1; string title = 2; repeated string snippets = 3; } repeated Result results = 1; } becomes two classes/structs `SearchResponse` and `SearchResponse_Result` in the target languages I've looked at. In Vim, you could do the same: interface Message endinterface class SearchResponseResult implements Message var url: string var title: string var snippets: list<string> endclass class SearchResponse implements Message var results: list<SearchResponseResult> endclass That seems the most straightforward approach to me. If you don't care about typing (but wouldn't that defeat the purpose of protobuf?), you may simply use dictionaries, which can be arbitrarily nested. If your problem is parsing, libparser might help: https://github.com/lifepillar/vim-devel Protobuf's grammar seems simple enough. You might even go fancy and generate parsers from messages, which would be able to parse the corresponding messages. I don't see any reason to keep using Vim legacy script for new Vim scripts.
