+    File Name:          12.6.3-12.js
+    ECMA Section:       12.6.3 The for...in Statement
+    Description:
+
+    This is a regression test for http://bugzilla.mozilla.org/show_bug.cgi?id=9802.
+
+    The production IterationStatement : for ( LeftHandSideExpression in Expression )
+    Statement is evaluated as follows:
+
+    1.  Evaluate the Expression.
+    2.  Call GetValue(Result(1)).
+    3.  Call ToObject(Result(2)).
+    4.  Let C be "normal completion".
+    5.  Get the name of the next property of Result(3) that doesn't have the
+        DontEnum attribute. If there is no such property, go to step 14.
+    6.  Evaluate the LeftHandSideExpression (it may be evaluated repeatedly).
+    7.  Call PutValue(Result(6), Result(5)).  PutValue( V, W ):
+        1.  If Type(V) is not Reference, generate a runtime error.
+        2.  Call GetBase(V).
+        3.  If Result(2) is null, go to step 6.
+        4.  Call the [[Put]] method of Result(2), passing GetPropertyName(V)
+            for the property name and W for the value.
+        5.  Return.
+        6.  Call the [[Put]] method for the global object, passing
+            GetPropertyName(V) for the property name and W for the value.
+        7.  Return.
+    8.  Evaluate Statement.
+    9.  If Result(8) is a value completion, change C to be "normal completion
+        after value V" where V is the value carried by Result(8).
+    10. If Result(8) is a break completion, go to step 14.
+    11. If Result(8) is a continue completion, go to step 5.
+    12. If Result(8) is a return completion, return Result(8).
+    13. Go to step 5.
+    14. Return C.
