That is at least partly because Javascript with statements are badly
broken. Consider the following code:
function setit(a) {
with (a) { x = 1; };
return a;
}
var x;
delete x;
alert(setit({'x':0}).x);
alert(setit({'y':0}).x);
alert(x);
If 'a' has a property 'x' setit updates the property, otherwise it searches
out the scope chain until it finds an object with an 'x' property and
finally creates one on the global object if there isn't one.
So the output in this case is the sequence '1', 'undefined', '1'.
