* 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

*
* 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."

// Run-time statements to pass to the eval inside f
sToEval += 'actual[0] = typeof g;'

/* 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'
