Update: I've proposed that we remove this oddity from the spec instead. :D https://github.com/tc39/ecma262/pull/1393 The above proposal reached consensus! Closing this ticket as no longer necessary. Will remove the corresponding FIXME. Committed r240686: <https://trac.webkit.org/changeset/240686> |
Annex B.3.5 exempts `try {} catch (e) { var e; }` from being a syntax error, but this exemption should not apply if the var declaration is a for-of initializer. Spec link: https://tc39.github.io/ecma262/#sec-variablestatements-in-catch-blocks
