It's the same as if you lambda-coded the above (here shown in JS1.8
[Firefox 3], note the expression closures):
function bar() {
function foo() 'local';
function zot() global.foo();
}
function foo() 'global';
This example uses ES4's global synonym for the global object, but you
could capture this in a global var at top level:
var global = this;
print(new bar().zot()); // print 'global'
in ES3 or JS1.8 to get the same effect.
You could use window["foo"](); or whatever the global object is
named in the environment
No need to quote and bracket, of course -- window.foo() is fine too.
