+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({})));
+```
