 That's because `this` is an object before the dot, so `rabbit.eat()` modifies `rabbit`.
 
 Property lookup and execution are two different things.
-The method `rabbit.eat` is first found in the prototype, then executed with `this=rabbit`

 There are only two limitations:

 Also it may be obvious, but still: there can be only one `[[Prototype]]`. An object may not inherit from two others.

-That's for data properties only, not for accessors. If a property is a getter/setter, then it behaves like a function: getters/setters are looked up in the prototype.
+Accessor properties are an exception, as assignment is handled by a setter function. So writing to such a property is actually the same as calling a function.
