  * 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

  * See http://bugzilla.mozilla.org/showattachment.cgi?attach_id=25251

  * See http://bugzilla.mozilla.org/show_bug.cgi?id=69441 (!!!)

  * 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."

 // Capture a reference to the global object -

 var self = this;

 // You shouldn't see this global variable's value in any printout -

 var x = 'outer';

 // This function is the heart of the test -

 function f(o,s,x) {with(o) eval(s); return z;};

 // Run-time statements to pass to the eval inside f

 sToEval += 'actual[0] = typeof g;'

 sToEval += 'function g(){actual[1]=(typeof w == "undefined"  ||  w); return x};'

 sToEval += 'actual[2] = w;'

 sToEval += 'actual[3] = typeof g;'

 sToEval += 'var z=g();'

 // Set the actual-results array. The next line will set actual[0] - actual[4] in one shot

 actual[4] = f({w:44}, sToEval, 'inner');

 actual[5] = 'z' in self && z;

 /* Set the expected-results array.

  *

  *  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'
