An @lru_cache is applied directly to an instance method. What does this reveal about its cache?
from functools import lru_cache
class C:
def __init__(self, v):
self.v = v
@lru_cache(maxsize=None)
def compute(self):
return self.v * 2
a, b = C(10), C(20)
a.compute(); b.compute()
print(C.compute.cache_info())
