Comment on attachment 261842 [details] patch View in context: https://bugs.webkit.org/attachment.cgi?id=261842&action=review r=me > LayoutTests/js/script-tests/let-syntax.js:70 > +shouldNotHaveSyntaxError("function foo() { { let x; } var x; }"); Nice! > LayoutTests/js/script-tests/let-syntax.js:105 > +shouldHaveSyntaxError("let x; var [x] = 20;"); I suggest adding `var x; let x;` cases because this issue depended on the occurrence order.
