--- Comment #30 from Matthew Hill <matthew.jh at outlook.com> ---
The code *should* be correct now.

The reason I thought Structures for empty objects with a given prototype were cached was because I saw `PrototypeMap::emptyObjectStructureForPrototype`... any reason we don't use that here? It seems a waste to re-create the same Structure more than once. I'm sure this code will still perform poorly if someone has an array of functions with the same non-Function.prototype [[Prototype]] when they come to bind them.
