…tantiation This PR completes a small bugfix from 9 years ago. Fixes tc39#2663. ---- History: 2015-07-17: @bakkot identifies a problem in Annex B's "Changes to FunctionDeclarationInstantiation": https://esdiscuss.org/topic/block-level-function-declarations-web-legacy-compatibility-bug To remedy this, @allenwb submits bug 4427: https://tc39.es/archives/bugzilla/4427/ in which he recommends changing > For each FunctionDeclaration _f_ **in _varDeclarations_** that is directly contained in the |StatementList| of a |Block|, |CaseClause|, or |DefaultClause|, to > For each FunctionDeclaration _f_ that is directly contained in the |StatementList| of a |Block|, |CaseClause|, or |DefaultClause| **Contained within _code_**, (emphasis mine). 2015-10-29: @anba submits PR tc39#141, claiming to fix bug 4427. It deletes "in _varDeclarations_", but doesn't add "Contained within _code_". My guess is, this was just an oversight. 2015-11-02: PR tc39#141 is merged to master as commit efbfc88. 2022-02-13: @nicolo-ribaudo raises issue tc39#2663 about this, and says he'd open a PR to fix it, but I don't think that happened. 2024-06-26: @gibson042 raises the problem again, in a commment on PR tc39#2952: tc39#2952 (comment)
