Coccinelle has also internally a fully elaborated AST and one can write any transformations in OCaml working on this AST but this is precisely what we want to avoid with Coccinelle. We don't want users to express their transformations on the AST but instead to express it easily using our SmPL patch syntax.

Also you didn't really answer my question, how long will it take using Pork to express the second program transformation mentioned in val's article about renaming malloc and also adding the pointer checking code for NULL.
