Trying to understand dyn trait limitations

I don't understand the limitation with static functions on dyn Trait's. My understanding of a dynamic trait is it passes a function pointer table of the trait functions alongside the object. I don't see how a static function cannot be added to this function pointer table.

This was discussed recently:

Explain why functions with no receiver are non-dispatchable?

How would you call it? The &self param is a fat pointer that contains the vtable pointer, so you need it to get the vtable.
