Have [Symbol.iterator] on the enum object

[Jack-Works]

Should we have a [Symbol.iterator] on the enum object?

enum A { B = 1, C = 2 }

for (const value of A) {
    console.log(value)
}
// logs: 1
// logs: 2

Problem

What if developers actually want to iterate on the key to get "B", "C" instead of 1, 2?

This feature conflicts with the feature Fully computed key in #11 because it's possible to write the following code.

enum A { [Symbol.iterator] = 0 }
