+/**
+ * Creates a tree of `WeakMap`-based cache nodes based on the identity of the
+ * arguments it's been called with (in this case, the extracted values from your input selectors).
+ * This allows `weakMapMemoize` to have an effectively infinite cache size.
+ * Cache results will be kept in memory as long as references to the arguments still exist,
+ * and then cleared out as the arguments are garbage-collected.
+ *
+ * __Design Tradeoffs for `weakMapMemoize`:__
+ * - Pros:
+ *   - It has an effectively infinite cache size, but you have no control over
+ *   how long values are kept in cache as it's based on garbage collection and `WeakMap`s.
+ * - Cons:
+ *   - There's currently no way to alter the argument comparisons.
+ *   They're based on strict reference equality.
+ *   - It's roughly the same speed as `lruMemoize`, although likely a fraction slower.
+ *
+ * __Use Cases for `weakMapMemoize`:__
+ * - This memoizer is likely best used for cases where you need to call the
+ * same selector instance with many different arguments, such as a single
+ * selector instance that is used in a list item component and called with
+ * item IDs like:
+ *   ```ts
+ *   useSelector(state => selectSomeData(state, props.category))
+ *   ```
+ * @param func - The function to be memoized.
+ * @returns A memoized function with a `.clearCache()` method attached.
+ *
+ * @example
+ * <caption>Using `createSelector`</caption>
+ * ```ts
+ * import { createSelector, weakMapMemoize } from 'reselect'
+ *
+ * interface RootState {
+ *   items: { id: number; category: string; name: string }[]
+ * }
+ *
+ * const selectItemsByCategory = createSelector(
+ *   [
+ *     (state: RootState) => state.items,
+ *     (state: RootState, category: string) => category
+ *   ],
+ *   (items, category) => items.filter(item => item.category === category),
+ *   {
+ *     memoize: weakMapMemoize,
+ *     argsMemoize: weakMapMemoize
+ *   }
+ * )
+ * ```
+ *
+ * @example
+ * <caption>Using `createSelectorCreator`</caption>
+ * ```ts
+ * import { createSelectorCreator, weakMapMemoize } from 'reselect'
+ *
+ * const createSelectorWeakMap = createSelectorCreator({ memoize: weakMapMemoize, argsMemoize: weakMapMemoize })
+ *
+ * const selectItemsByCategory = createSelectorWeakMap(
+ *   [
+ *     (state: RootState) => state.items,
+ *     (state: RootState, category: string) => category
+ *   ],
+ *   (items, category) => items.filter(item => item.category === category)
+ * )
+ * ```
+ *
+ * @template Func - The type of the function that is memoized.
