On registration you have a priority. Registration errors if two functions are registered with the same priority. Result: total ordering between registered hook functions. Each hook can return one of three values: everything ok; non-fatal error; fatal error. > - Do we want to make it possible to give a priority to hook functions? > That would require a priority parameter to add_hook(). Yep. See above. > - Do we want a third function that returns information about a hook, > such as how many functions are attached and their identities (the id > returned by add_hook()), and whatever other data there may be. How do imagine this to be used? I don't see the value of it from the hook's perspective, and whilst it could be valueable to a user, if the user doesn't know what hooks they have registered then they have other problems. > - Do we want to be able to identify some hook functions by name? Probably useful with regard to error reporting.
