Subject: | [Caml-list] about Obj.magic |
Hi, all, When should I use 'Obj.magic'? It is really confusing. Now I am converting a bunch of code from sml to ocaml. During the process, I want to make sure that the type of every function keep consistent with the original one. But I still encountered a lot of problems about the types in ocaml. For examples, all my base functions are fine in ocaml. But, sometimes when I tried to combine a few base functions together in the same way as my original code, I got a type error. After endless trial, I have to use 'Obj.magic'. In some sense, it is good because I can compile my code now. On the other hand, things will be worse because it is very difficult to debug if I use a few 'Obj.magic' in my code. I couldn't find out the origins of all the runtime errors. So, we should be very careful to use 'Obj.magic'. Can somebody tell me the appropriate situation to use this function? Thanks a lot!
