Right, that capture-in-prototype case does not differ due to both
cascade desugaring and 'with' searching the head object including its
prototype chain.
But with a deeper scope chain, and bar not bound in the innermost scope,
then 'with' allows an evil interloping function to shadow (or delete if
configurable) along the scope chain.

Whereas with cascades, you'd get:

with (obj) {
log(bar); // local variable
foo();
log(bar); // local variable
}
Oh for crying out loud. Of course I meant:
var obj = {
log: console.log.bind(console),
foo: function() { Object.prototype.bar = "captured" }
};
var bar = "local variable";
obj.{
log(bar); // local variable
foo();
log(bar); // captured
}
