ES5 11.13.1 Simple Assignment (=)
The production AssignmentExpression : LeftHandSideExpression = AssignmentExpression is evaluated as follows:
1. Let lref be the result of evaluating LeftHandSideExpression.
2. Let rref be the result of evaluating AssignmentExpression.
3. Let rval be GetValue(rref).
...
6. Return rval.
Simple assignments ALWAYS return the right hand!
(keep a copy of ES standard on your desk, it WILL help you)
