Using args directly as a dictionary key can lead to issues because args is a tuple, which is hashable, but if any of its elements are mutable (like lists), it will cause a TypeError. Consider converting args to a hashable type that only contains immutable elements, or ensure that the function only accepts immutable arguments.

return storage[args]
else:
result = func(*args)
storage[args] = result
print("Calculating new result")
