Yes, I do know Go predates a solid description of the paradigm, though I hid that in what otherwise looks like a bizarre verb tense in my first sentence. :) Pa

Yes, I do know Go predates a solid description of the paradigm, though I hid that in what otherwise looks like a bizarre verb tense in my first sentence. :) Part of the reason I rhapsodize about new languages off of that observation is precisely that Go can't add it. It almost wouldn't even matter if they tried to put it in the language proper, because by backwards compatibility the old ways would still work, and it would take a very long time to get the entire ecosystem to the new way.
