Let's back up.
You and I know we can't incompatibly change the language. So "use
strict" or better ("use lexical scope", or just the default in a
future opt-in version based on the Harmony proposals) will be
necessary to get the right non-default-but-built-into-browsers
behavior, where free variables are static errors. Anything else is a
new Web, e.g. Flash or Silverlight.
Unless you have a better idea?
Nope. I'm only suggesting that we need to get to "use better_thing"
SRTL and that ES5 strict mode doesn't fix the problem in an
appreciable way for most content. I expect we're in agreement.
