<pre>The following code in Source/JavaScriptCore/runtime/JSFunction.cpp, added in 2011, could use some investigation/auditing:
```
// This will trigger the property to be reified, if this is not already the case!
bool okay = thisObject->hasProperty(exec, propertyName);
ASSERT_UNUSED(okay, okay);
scope.release();
return Base::put(thisObject, exec, propertyName, value, slot);
```
It's unclear what the purpose of reifying this is, as the properties in question are not lazy. Base::put() ought to be enough.</pre>
