I wonder if something like Ruby could fit into this category too, even though there isn’t a clean line between the two phases. (I’m stretching the concept a bit heh) The block inside of a class or module definition is executed first, and then the application can work on the resulting structure generated after that pass. Sorbet (a Ruby static typing library) uses this first-pass to generate its type metadata, without running application code. (I think by stubbing the class and module classes themselves?)
