Are you talking about all methods or just ArrayAccess?
If you're talking about https://github.com/gtkphp/php-ext-gtk-src/blob/master/php_glib/hash-table.c
it's possible to associate the table of overridden methods with the instance of the object,
and look it up in a C property of `intern->methods` to call the overridden method.
- If you're talking about avoiding doing a hash table lookup on every method call to an instance, you can use a `methods` property.
https://github.com/php/php-src/blob/PHP-8.1.0/ext/spl/spl_fixedarray.c#L241-L301 does that - see create_object, spl_fixedarray_new, and `spl_fixedarray_object *intern;`
(I implemented that in https://github.com/php/php-src/pull/6552)
It turns out review comments mentioned something similar about `ArrayAccess`.
At the time I wasn't as familiar with how it'd be done for all classes and work with inheritance, though I think it's possible.
- If `arraylike_funcs_ptr` were added to php for ArrayAccess, `instance->ce->arrayaccess_funcs_ptr->offsetget->scope != my_base_class_entry` could be used to check if the internal implementation was overridden
> Ideally these methods would be cached in the class_entry, but that's a larger change.
```c
// Declared in Zend/zend.h
// Initialized in Zend/zend_interfaces.c
// ....
/* allocated only if class implements Iterator or IteratorAggregate interface */
zend_class_iterator_funcs *iterator_funcs_ptr;
```
