      @wycats @stefanpenner Hey is it too late to fix ES6 behavior for this? fn = () => { x: 42 } x is a label here, fn returns undefined :(

      @wycats @stefanpenner May not be possible to make it an object because () => {} can't change, but surely error is better than silent label?

      @wycats @stefanpenner Seems like pretty big footgun; fails silently, and most people don't even know labels are a thing. /via @briancavalier

      @wycats @stefanpenner To be precise, I'm proposing that labels at the beginning of `=>` blocks be syntax errors. (thanks @terzicigor)

      @wycats @stefanpenner Hey @BrendanEich, I liked your strawman in https://esdiscuss.org/topic/x-foo-bar  with UnlabeledStatement, disallowing () => {x: y}.

      @wycats @jo_liss @stefanpenner We know of stray labels in Web JS, especially "javascript:" (in mid-file even). Worth a revival post, thanks.

      @BrendanEich @jo_liss @stefanpenner Could it be retrofitted onto strict mode? Might be web compat.

          @wycats @BrendanEich @jo_liss @stefanpenner My spidey sense is unclear on whether it might even fly for the whole web, not just strict mode.

          @wycats @littlecalculist @BrendanEich @jo_liss @stefanpenner wouldn't arrows be new code, thus likely to be fixed quickly?

          @wycats @jo_liss @stefanpenner Yeah, since strict mode (prior to ES6 modules) is underused, might well fly.

          @BrendanEich @jo_liss @stefanpenner it's underused *especially* by people who do crazy things like cargo cult `javascript:` into a program

          @wycats @jo_liss @stefanpenner not cargo cult AFAIK -- just copy-paste and concatenation.

          @wycats @jo_liss @stefanpenner 1/ Context-blindness if not copy/paste helped people write onclick=`javascript:...` too. Again copy-paste is

          @wycats @jo_liss @stefanpenner 2/ most parsimonious explanation, because in Netscape 2 some elements lacked onclick but had href= or src=.

          @BrendanEich @jo_liss @stefanpenner better explanation, but still unlikely to occur in people opting in to strict mode in 2015 :)
