I wrote tests with and/or that included a parse error in the second part of the operator. Since we were expecting these operators to evaluate sequentialy, I was expecting the parse error to not be hit when the first part of "and" evaluated to false and when the first part of "or" evaluated to true but that was not the case.

See tests:
test_sequential_and_01
test_sequential_or_01
