Why doesn’t Perl have a symbolic logical xor operator (spelled “^^”)? As far as I can tell, the only reason is that C doesn’t have one...
At a minimum,
it would remove the need for parentheses in expressions like
$flag = ($subflag1 xor $subflag2);
$flag = $subflag1 ^^ $subflag2;
…like you can now do with and and or, as long as you spell them “&&” and “||”.
Would I use this a lot? No. (I would have for maybe the 2nd time yesterday, which is what made me think of it.) But as someone who loves completeness, the absence of a symbolic xor absences from Perl has always bothered me.
