michael@0:  * of  a Program by eval to create a property of eval's caller's variable object.
michael@0:  * This test evals in the body of a with statement, whose scope chain *is*
michael@0:  * relevant to the effect of parsing the FunctionDeclaration."

michael@0:  *
michael@0:  *  Sample issue: why do we set expect[4] = 'inner'?  Look at actual[4]...
michael@0:  *  1. The return value of f equals z, which is not defined at compile-time
michael@0:  *  2. At run-time (via with(o) eval(s) inside f), z is defined as the return value of g
michael@0:  *  3. At run-time (via with(o) eval(s) inside f), g is defined to return x
michael@0:  *  4. In the scope of with(o), x is undefined
michael@0:  *  5. Farther up the scope chain, x can be located as an argument of f
michael@0:  *  6. The value of this argument at run-time is 'inner'
michael@0:  *  7. Even farther up the scope chain, the name x can be found as a global variable
michael@0:  *  8. The value of this global variable is 'outer', but we should NOT have gone
michael@0:  *      this far up the scope chain to find x...therefore we expect 'inner'
