Questions about 'metaprogramming-in-es6-symbols' article

gistfile1.md

On the section about Symbols not being truly private:

assert.deepEqual(Object.getOwnPropertySymbols(x), [Symbol(size)]); I was expecting: assert.deepEqual(Object.getOwnPropertySymbols(x), [size]);

Is it required to call Symbol(size) to have proper comparison even though size is already an instace of Symbol?

On the section about Symbol.match:

return [find]; I was expecting: return [this.value];

Thanks again!
