Using args directly as part of the dictionary key can lead to runtime errors if any of its elements are mutable. Consider converting args to a fully hashable type, such as a tuple, to ensure that the key is always hashable.

if key in storage:
print("Getting from cache")
return storage[key]
else:
result = func(*args, **kwargs)
storage[key] = result
print("Calculating new result")
return result

return wrapper
