<pre>This doesn't seem spec compliant to me:
```
function foo() { function bar() { return x; } var x = Object.getOwnPropertyDescriptor(Object.prototype, "__proto__").get; return x(); }
foo() // [object Object]
```
```
function foo() { var x = Object.getOwnPropertyDescriptor(Object.prototype, "__proto__").get; return x(); }
foo() // Exception: TypeError: Can't convert undefined or null to object
```</pre>
