      of my concerns that leaky inner control abstraction defining break/continue targets would be a huge footman.

      It’s basically dynamic scoping problem. Unlabeled break/continue may not be intended for closest dynamically enclosing break/cont-able loop

      Not dynamic scope: a dead outer activation causes return from block lambda to throw. Dynamic scope analogy would be return from unrelated!

      let b= ƛ(v){if (v) break; else continue}; are these different: forEach(c, b); forEach(c, ƛ(v){if (v) break; else continue});

      Correspondence principle deal is program equivalence: while(1)break === while(1)({|| break})(). Variable abstraction independent/composes.

      Too hard to show on twitter. Have to get into guts of forEach, etc. to show how they compose. My pdf was a start.

      Yes, agree this exposes/specifies “guts” - one reason among several that block lambdas failed.

      Give me another chance and I'll fight my ass off. Otherwise, the frequent justifications for the decision aren't that helpful.

      Replying to @wycats @awbjs and

      Read closely, justifications strong. No way: dynamic throw-like return/break/continue. Static better but dead frame return throws hazardous.

      You have to do better than "return from dead frame hazardous" when Ruby has the same hazard and doesn't create too much confusion.

      Here's what I was told back in 2012 by a committee member before I was on the committee. Very poor argument, but a winning one.pic.twitter.com/BFWGuoWbpE

          That was not canonical death blow to control effects equivalence - see older https://www.mail-archive.com/es-discuss@mozilla.org/msg01533.html … from @othermaciej.

          I think you agree that this perspective was a key one in ultimately defeating the proposal. Others came to terms, this was there to the end.

          Block lambdas died in part because a committee member thought let scope was (forever) too unpopular to use as a pun. 😢

          No, Alex’s objection was not what killed block lambdas. He isn’t in charge anyway!

          Alex was never going to agree. Arrows were a good enough compromise. Of that there is no doubt.

          Alex was not alone in objecting to block lambdas and others shared Maciej’s objection. Block lambdas lost.
