I understood it to just asking for an explanation of those concepts are, rather than how they're implemented. As for "exposing the implementation", while I don't really like it we do already document it in the Elisp manual: -- Function: run-hooks &rest hookvars [...] If the hook variable is buffer-local, the buffer-local variable will be used instead of the global variable. However, if the buffer-local variable contains the element ‘t’, the global hook variable will be run as well. -- Stefan
