An annual conference sounds like a great opportunity to discuss design
goals of languages and long term goals - I am a much less ambitious
man than you. I'm just thinking of small scope examples, to name 3 on
top of my head:
- The iteration protocol (PHP had a similar lengthy discussion about
something like our `return` - talking to the relevant people there
would have helped).
I know Rasmus Lehrdorf and saw him in Taipei in May. But I think you may
be missing the long history, going back to ES4, of the iteration
protocol that went into ES6. I based it on Python 2.5, and then Igor
Bukanov (at the time a peer on SpiderMonkey) worked hard to improve the
Pythonic design to eliminate GeneratorExit. Here is Igor in the
python-dev list:

Here is Phillip J. Eby replying to Guido and giving a nod of approval to
Igor's solution of forcing a return instead of throwing GeneratorExit:

See, we did actually do our homework and get into the guts of the other
language. :-P
(In the end, what got the iteration protocol buy-in across TC39 was Dave
Herman's elimination of StopIteration. So Igor and I should have worked
harder to eliminate exception singletons (a smell for sure). :-P to me
too :-D. I'm still waiting for the {value, done} record object to be
optimized away in modern engines, so :-P to them.)
I agree that this kind of diligence is required. I don't see how a
gab-fest helps, though. It can help forge social bonds across
communities, and it doesn't hurt for other reasons, but it is not the
place for detailed grunt-work.
