* lacks tests
* should raise exceptions when provided with illegal arguments (`func` must be a function, `cache` a dict, and `num_args` a positive integer)
* should raise an exception if any of the arguments of `func`, which are used as dictionary keys, is unhashable"	Cleanup/optimization	closed	Utilities	dev	Normal	fixed		bmispelon@… Bouke Haarsma	Accepted	1	0	0	0	0	0
