Yes! There is an serious bug! It's illegible, unreadable, illogical,
incomprehensible, dirty, heavy, ..
It's a testcase for humans but there is not a testcase for the machines.
For instance,
why loop_invariant_p and consec_sets_invariant_p are predicates
(or boolean functions)?
why use them inside of an logical expression?
The source code had exposed logical operations with not 2 values 0 and 1,
with 3 values 0, 1 and 2!
