    As choroba said, return 1&&0 is different from return 1 and 0.

    $ perl -MB::Deparse -e' sub f{return 1 and 0;}; sub g{return 1 && 0}; $deparse=B::Deparse->new(); print "f(): ",$deparse->coderef2text(\&f),"\n"; print "g(): ",$deparse->coderef2text(\&g),"\n";' f(): { 0 if return 1; } g(): { return 0; }

      I think it's bad design
        It makes
        open my $FH, '<', $filename or die $!;
        and is similar to shell's
        mkdir $dir || exit 1
        But, of course, you can think whatever you want.
