Ok I misinterpreted what you previously said then. I think Swift does this because they only have a single function pointer type which serves all purposes while FPC has 4 distinct types. IMO FPC needs this also since it's not possible for libraries to know which kind of function the caller may provide. Behind the scenes the different types are required (global, nested, method, reference) but there should be a way to unify these into single type. How to store the capturer and manage its memory would be an open question though.
