[Tucker has a fix, but for those of you who are curious about the js  
semantics here:]

If it did, that would just be indicative of another bug.  'var' in js  
has function scope no matter where it occurs within the function, so  
the following two programs have identical semantics:
    function f() {
     with (this) {
       var x=1;
     }
   }
   function f() {
     var x;
     with (this) {
       x=1
     }
   }

This is weird, and it's different from C(++) and Java where f() below  
has two different local variables (with the same name), and is  
therefore equivalent to g():
   void f() {
     {int a = 1; do_something_with(a);}
     {int a = 1; do_something_with(a);}
   }
   void f() {
     int a, b;
     a = 1; do_something_with(a);
     b = 1; do_something_with(b);
   }

But it is what it is.
