Mark is cheap. > I never knew them, thank you. On first sight Callouts look like an internal API, and otherwise, like they mean bad language integration. Anyway, when speaking of features, it is distinct. I believe enumerations attend a common case, that's why I posted the request. I can see it breaks the "always returns a list of strings" contract of the output. Breaking that contract will probably mean it'll never get implemented. But maybe I'm wrong. The result of an enumeration could of course be returned as the length field of a string, so at least things won't break for anyone upgrading to the latest version, ignorant of this feature. Anybody else could use the upgraded API. We could argue about the content of this backwards compatible string. It might signal that this is not an ordinary string, so zeroes and BACKSPACE come to mind. But maybe just leave it as a string of '#'. -- Configure bugmail: http://bugs.exim.org/userprefs.cgi?tab=email -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
