about up-thread. Oh what a tangled web we weave.
Yes, current thinking is that we should take the erratum that major JS
engines already fixed, and include it in ES6. But this means we must do
something different in WebIDL, probably make own global properties for
window-implements-interface-inherited attributes and even operations.
And then (for strict mode) be careful about get-only accessors. This
reminds me of [Replaceable], which was for non-writable but configurable
data properties that var and function must be able to replace. It's kind
of the opposite and only for accessors:
var-captures-own-accessor-via-detection, or some such.
Just recapping, tell me if I'm missing something.
The above sounds like a reasonable summary to me. Certainly hits all
the high points of the discussion, with the addition that the GSP as
currently specced depends on the erratum sticking around.
