HOOK_theme() fits the criteria you outlined, except for one item: &quot;It takes no parameters.&quot; </blockquote><div><br>Many other hooks also have no args, module_invoke_all has been able to support 0-n args for a long time. This is a problem long since solve in php and in various parts of drupal already. func_get_args, call_user_func_array(), etc...<br>

Of course, HOOK_theme() is a special case since themes (and not just modules) can call that hook. (And, btw, themes can&#39;t call the corresponding HOOK_theme_registry_alter().)</blockquote>
<div><br>Themes can all call any hook. This is not a special case.&nbsp; Really you&#39;re going to have to explain, &quot;themes can&#39;t call the corresponding HOOK_theme_registry_alter()&quot;. Why not?<br>&nbsp;</div></div><br>
