 We use this as part of a persistent cache key:
 serialize($GLOBALS['wp_filter']['list_terms_exclusions']). See [8225].

 This is not good for two reasons. First, well, it's a not fun to reach
 into our internal API like that. But worse, it's broken whenever an object
 method is used, because spl_object_hash() will be unique to that object,
 thus rendering the cache invalidated on the next pageload.

 As an aside, we should probably have _wp_filter_build_unique_id() create a
 delimiter when dealing with a static class method —
 `$function[0].$function[1]` can conflict with a legitimate function name.

 I'm not sure how this should be fixed.
