print "Valid" unless (
    (0  < 0 || 0 > 0) ? 1
  : (0  < 0)          ? 1
  : (0 >= 1)          ? 1
  : 0
)


This concept really goes against the perl grain in
that 0 = false, >0 = true.

Especially when the writer is not sure whether
0 is true or not.  A beginner can themselves
into a corner where they are no longer sure
what the goal was...
