I disagree with Brendan when he says "to use weakmaps for class
private instance methods/variables"... well... it depends on what
"use" means:
The spec is allowed to /use/ anything it needs to make the class
private syntax work. If the spec says that private properties are like
properties but aren't enumerated in Object.gOPN calls, fine. If the
spec says that private properties require a lookup to some object ->
value map, fine (but misleading, I agree).
I don't think we disagree.
If there were no observable differences at all between weak maps and
private symbols, we would have only one. Since there are, and since you
propose to map private-in-class syntax onto weak maps in part on account
of these differences (viz, proxying and whitelist population without
privacy-leaks), here we are.
Perhaps I should have written "utilize"? Bleah.
