Comment on attachment 404216 [details] Add support for static private fields Can you rebase and fix EWS failures?

(In reply to Yusuke Suzuki from comment #3) > Comment on attachment 404216 [details] > Add support for static private fields > > Can you rebase and fix EWS failures? Hey! Maybe it was not totally clear from the first comment, but this patch needs the static public fields patch in bug #194095 to apply, so can't really fix EWS until that one lands. Just uploaded it for reference, that's why it was not flagged as r?. Will get on it when possible for sure!

I also miss a test that verifies if instance of a class can't access static fields. Do you mind adding them if they are missing?

Let's add $vm.isPrivateSymbol and use it here.

This is going to break whenever we call `isPrivateSymbol(x)` and x is not a Symbol. We should just call `asSymbol` when we are sure that JSValue is a Symbol. I think what you meant to use here is: ``` ... if (!callFrame->argument(0).isSymbol()) ... ```
