I wondered why we decided to use CanDeclareGlobalFunction/CreateGlobalFunctionBinding instead of CanDeclareGlobalVar/CreateGlobalVarBinding, and look what I found -> https://bugs.ecmascript.org/show_bug.cgi?id=4428#c1. 😄 I think @syg should take a look at this change to confirm that this matches what he implemented in SpiderMonkey. |

I'm pretty sure the PR matches my implementation. Sorry I completely forgot to respond to this. |

I think TC39 was happy with this sort of thing ultimately, right? |

I believe we got consensus here. Aside from addressing code review feedback on the tests, does anything else need to be fixed up for this patch to land? |
