 * 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."

// 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;'

/* 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'
