function test(){

    async function foo(x) {

        const S = Set;
        const A = Array;
        const R = Reflect;

        const Sym = Symbol;
        const Boo = Boolean;
        const JS = JSON;
        const ev = eval;

        for (let i = 536870912; i < x; i = i ** x) {
            const f = await foo;
            const s = i.splice();
        }

        async function bart() {
            const w = new WeakMap();

        }
        const ret = bart();
    }

    const r = foo();
    return r;
}

for(let i=0; i<1024; i++)
{
