22* SUMMARY:  self.eval(str) inside a function
23* NOTE: 'self' is just a variable used to capture the global JS object.

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

67/* Set the expected-results array.
68*
69*  Sample issue: why do we set expect[4] = 'inner'?  Look at actual[4]...
70*  1. The return value of f equals z, which is not defined at compile-time
71*  2. At run-time (via with(o) eval(s) inside f), z is defined as the return value of g
72*  3. At run-time (via with(o) eval(s) inside f), g is defined to return x
73*  4. In the scope of with(o), x is undefined
74*  5. Farther up the scope chain, x can be located as an argument of f
75*  6. The value of this argument at run-time is 'inner'
76*  7. Even farther up the scope chain, the name x can be found as a global variable
77*  8. The value of this global variable is 'outer', but we should NOT have gone
78*      this far up the scope chain to find x...therefore we expect 'inner'
