You’d probably want to use either some sort of code generation to do the requisite CPS transform[1] or the Duff’s-device-like preprocessor trick[2], but it’s definitely doable with some compiler support. Not in an existing codebase, though.
(Brought to you by working on a C codebase that does express stuff like this as explicit callbacks and context structures. Ugh.)
