I just read Synopsis 3, and I have several questions.
1) Synopsis 3 says that the difference between $x ?| $y and $x || $y is that the later always returns a Boolean. Does this mean that $x ?| $y short-circuits? 2) Do all of the xor variants have the property that chained calls return true if exactly one input parameter is true? 3) Is there an ASCII digraph for the | operator? 4) Do "==" and "!=" participate in chained comparisons, so that $a == $b == $c evaluates to true if and only if all three are equal? Is $x > $y < $z a legal chaining? Or $x < $y lt $z? 5) Would it be possible for me to create a user-defined operator that does chaining? Joe Gottman
