It's not possible, any closure only has access to the variables in scope
when it is defined.
function foo(a,b,c,f)
{
var bar = function() {//has access to everything in foo}
function baz() {//Same as above}
}
var bash = function() { //Does not have access to what's in foo() at any
time}
foo(1,2,3,bash) //Doesn't suddenly give access to foo's locals.
Think of it this way - if what you wanted were possible, then what would
happen if I just invoked bash() instead of passing it to foo()?
There are tricks to achieve something similar to what you want, but they
require changing foo(), in which case you only need to pass arguments to the
f() function.
