Maple has developed a sophisticated strategy to ensure that the experience of its users is one of hopping from bug to bug.

It is based on two pillars: To change basic definitions (which are in fact fixed since Euclid) from time to time, and, secondly, to rely on the fact that their long-time users can't always adapt that quickly.

A nice example with the current Maple version (2023) is:

restart; with(numtheory): 
A027375 := n -> local d; add(mobius(d)*2^(n/d), d = divisors(n)):
seq(A027375(n), n = 1..9);

> 2, 2, 6, 12, 30, 54, 126, 240, 504

restart; with(NumberTheory): 
A027375 := n -> local d; add(Moebius(d)*2^(n/d), d = divisors(n)):
seq(A027375(n), n = 1..9);

>  2, -2, -2, 0, -2, 2, -2, 0, 0

If you have nothing better to do, you can waste your time trying to find the bug.
