There was a problem hiding this comment.
As long as calling to this NamedPropertyHandler is unobservable from JavaScript world - looks good to me!

@ak239 It doesn’t – it might call into JS, however. Your comment gave me the idea to add a test for when that JS code has a side effect – thanks! |

Nice test! As implementer of this side effect free eval in JS - any other calls to JS world should be fine, since they will contain the same side effects check, so getter without side effects should work, even getter that creates temporary objects and modify them will work. |
