um
data:text/html,<script src="data:text/javascript,function a() {b()
}"</script><script src="data:text/javascript,function b()
{alert('ouch') }"</script>
to the extent that a script can affect any variable that is reachable,
it does apply to all other scripts and certainly if i replace a
primitive object property/method i'm affecting future scripts.
Sure you could argue that the object file example is accurate if you
remind people of ld preloading and symbol shadowing etc., btu most
people wouldn't think about it that way.
