in thread Can you explain the result?

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.

        The real problem is that return is pretty different than ordinary subs like open and etc...
