In many cases one needs an additional 'indirection' to return
a value that is simply one of the two truth values. Since it's
often a case of trial and error to figure out whether in-line-if's are fully
evaluated to one of the two values (at least with my Maple 9) I'm in
almost all cases wrapping these binary evaluations into if-then-else-clauses.
And, in addition, I'm never trying to squeeze all code into one-liners...
