+### LRU Cache
+**Decorator that caches functions return values.**
+```python
+@lru_cache(maxsize=None)
+def fib(n):
+    if n < 2:
+        return n
+    return fib(n-1) + fib(n-2)
+```
+
+```python
+>>> [fib(n) for n in range(16)]
+[0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610]
+>>> fib.cache_info()
