I'm late to this party, and maybe this discussion has already gone on too
long. If so, I'm sorry for dredging it back up.
But I'm curious about where Tim was going with this, because I feel like I
might be missing out on a great idea:

I'm trying to match this up with my personal experience, and I think that's
probably lacking.
Based on Jeanine's talk, I almost think that the real context here is
language design. I got the impression that we could probably also gain
benefits in network protocol design. (Someone mentioned this earlier in
terms of REST and HTTP, but I think there are probably broader
implications).
I'm generally in favor of the "just stick it into a map" approach. But I'd
love to hear from people with "That didn't work out well" experience.
Assuming there are any.
Thanks,
James
