I was thinking that the semantics of "and" & "or" are the replacement
for the trinary operator? Since these operations always return the last
evaluated subexpression (the same subexpression that short-circuits the
evaluation), they can be used as Gerald outlines above. It seems very
consistent, logical, and understandable to me; but then again, I love
the semantics of list compressions. ;)
