Can't use aliases of the global `Symbol` value to refer to its properties in the same manner or create unique symbols

Although Nodejs also uses this technique, we can’t do the same thing.

Code

export { }
const Symbol = globalThis.Symbol;
const sym = Symbol();
[][Symbol.iterator];

Expected behavior:

const sym = Symbol(); // typeof sym
[][Symbol.iterator]; // Refer iterator method

Actual behavior:

const sym = Symbol(); // symbol
[][Symbol.iterator]; // error

Can’t use aliases of the global Symbol value to refer to its properties in the same manner

And can’t make unique symbols using an alias of the Symbol function. Don’t miss it.
