Thanks for the pointer.  I still don't understand all of the tc39 process.

Though the const declaration requires an initializer, there is still a sentinel AFAIU.  See for example the V8 mail I linked to before, or Brendan's reply to that.

Well, I'll take a look again.  I was basing my interpretations on es-discuss proceedings from the last month or so.

Thanks for the valuable feedback, though it does make me a little less sure of what the spec is right now ;)
