+ * SUMMARY:  self.eval(str) inside a function
+ * NOTE: 'self' is just a variable used to capture the global JS object.
+ *
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=68498

+ * Brendan:
+ *
+ * "ECMA-262 Edition 3, 10.1.3 requires a FunctionDeclaration parsed as part
+ * of  a Program by eval to create a property of eval's caller's variable object.
+ * This test evals in the body of a with statement, whose scope chain *is*
+ * relevant to the effect of parsing the FunctionDeclaration."

+ *
+ *  Sample issue: why do we set expect[4] = 'inner'?  Look at actual[4]...
+ *  1. The return value of f equals z, which is not defined at compile-time
+ *  2. At run-time (via with(o) eval(s) inside f), z is defined as the return value of g
+ *  3. At run-time (via with(o) eval(s) inside f), g is defined to return x
+ *  4. In the scope of with(o), x is undefined
+ *  5. Farther up the scope chain, x can be located as an argument of f
+ *  6. The value of this argument at run-time is 'inner'
+ *  7. Even farther up the scope chain, the name x can be found as a global variable
+ *  8. The value of this global variable is 'outer', but we should NOT have gone
+ *      this far up the scope chain to find x...therefore we expect 'inner'
