// what needs to be changed in this code, to satsify requirements below:
function () {
    function foo() {
        var a = 42,
            b = function () { console.log('hi'); };
    }
    // a and b should be available in this scope (but not the outter)
    // No other modifications to this scope are allowed
    function bar() {
        // could use a, b.
    }
}
