You don't add properties to the strings object, but use is as a key into a WeakMap.

  The strings object doesn't seem to differ based on call site. > f = l => l [Function: f] > f`hi` === f`hi` true

    What JS VM did you use? Edge/Chakra has a bug, but it's been fixed. That expression should return false in Chrome, Safari and Firefox.
