assert(!isWeakRef(function () {}));
assert(!isWeakRef(null));
assert(!isWeakRef(function* () { yield 42; return Infinity; });
assert(!isWeakRef(Symbol('foo')));
assert(!isWeakRef(1n));
assert(!isWeakRef(Object(1n)));

assert(!isWeakRef(new Set()));
assert(!isWeakRef(new WeakSet()));
assert(!isWeakRef(new Map()));
assert(!isWeakRef(new WeakMap()));

assert(isWeakRef(new WeakRef({})));

class MyWeakRef extends WeakRef {}
assert(isWeakRef(new MyWeakRef({})));
