 Currently, when you're designing a theme or plugin, any malformed
 functions or the malformed hooks that activate them can throw this error:

 Warning: call_user_func_array() expects parameter 1 to be a valid
 callback, function '' not found or invalid function name in
 /home/user_name/user.web.site/wp-includes/class-wp-hook.php on line 292

 Core is not the cause of the error. My in-development plugin is.

 It would be more helpful if this error were caught in such a way that
 theme and plugin designers could be told in the debug.log exactly
 ''which'' line in theme's or plugin's function.php is causing the error.
