Here is my question: Is there any way to declare a module-local variable without using .mli signature? It may not be prefarable for direct use by OCaml programmers (than signature approach), but is useful for camlp4 programmers to avoid name crashes caused by "open" or "include" directive. P.S. I have implemented a more powerful syntax extension for regular expression matching, and I'm now preparing a documentation. I'll release it for caml-list within this month (hopefully). -- Yutaka Oiwa Yonezawa Lab., Dept. of Computer Science, Graduate School of Information Sci. & Tech., Univ. of Tokyo. <oiwa@yl.is.s.u-tokyo.ac.jp>, <yutaka@oiwa.shibuya.tokyo.jp> PGP fingerprint = C9 8D 5C B8 86 ED D8 07 EA 59 34 D8 F4 65 53 61 ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
