however much i respect peter, i disagree here. and/or are low precedence
and work well here but using them for completely different assignments
just to make a single statement is overkill. maybe in a one liner but
how many one liners need code this complex (if needed, it shouldn't be a
one liner). the code here should be a classic if/else and no other way.
