      Control flow in expression position makes me :(. Not allowed in `eval`, e.g. Why is that a thing you'd want? 1/

      `for (let a of b) { fn(a, y, do {if (cond) continue; z;}); }` = sadness. 2/2

      Worse: `for (x; do { if(cond) continue; a; }; y) { ... }`. What's the use case for control flow, to justify language complexity? 3/2

      it might actually be harder to disallow in terms of complexity, but also, returning seems quite useful.

      Harder on spec or implementors? Spec yes, but worth it I think. Doubt for implementors. What's the use case of returns in expr. pos?

      have you ever tried to write: x || throw new Error("...")? I have, many times.

      I'm fine with throw! Arbitrary exprs, iifes already can throw. Concerned about return, break, continue. Don't see use case, either.

      "can throw", not, "can contain a ThrowStatement". I'm fine with / happy about `do { throw new Error(); }`. But `return`?

      in Ruby I write code like this plenty: let result = if http://x.zero ? return last else recur(x) end Problem?

          That gives 'error: void value expression', no? With good reason. Doesn't this express intent better? Or do I not understand intent?pic.twitter.com/8juX55TZKS

          sorry -- let me try to be less terse soon. Heading in to work.

          Yeah, this medium isn't great for non-terseness. IRC (jslang or wherever) works too, if you'd prefer.
