I updated this too because block scoping rules for var mean that it wasn't working as expected

I am all for this but wondering whether we should cut a major in case somebody uses the bundler plugins for apps in an env where const isn't a thing yet.

I don't mind which way we go but we should either:

  1. Use var and wrap in self-invoking function
  2. Use var and wrap in try/catch
  3. Use block-statement with const or let

typeof window !== "undefined"
? window
: typeof global !== "undefined"
