As TypedDictionaryArray implements ArrayAccessor too, we can use compare_op to replace this compare_dict_op. So removing it here.

Nice 👍. This will make the codegen explosion worse, but I'm not really sure there is much we can do about that....

As pointed out by @pvsri #2564 (comment) this change introduces unsoundness, as dictionary indexes aren't always valid. I will have a think about how best to handle this

Should we just call self.values.value instead of value_unchecked in ArrayAccessor.value_unchecked of TypedDictionaryArray? It might be less performance, though.

No, because that will panic... I'm working on a fix - standby
