Or just
 var foo = {get bar() { return 10; }};

For consistency with the bug report I will leave this as is

+
+assertDoesNotThrow("foo.bar = 20");
+
+function shouldThrow() {
+  'use strict';
+  foo.bar = 20;
+}
+
+assertThrows("shouldThrow()");

This test doesn't seem to be as thorough as the one for not throwing - no
indexed properties/elements, no variable lookup (from with or global object).
Please add the other cases too.

[Rico, 2011/05/25 07:59:28]

I added the similar test cases to the original file (seems more appropriate).
Except for the 'with' case, since this is not allowed in strict mode :-) 

[Lasse Reichstein, 2011/05/25 09:10:25]

You can make a with around a strict function:
 with ({get foo() {}) {
   (function() { "use strict";
      foo = 42;
    })();
 }
