That's an immensely huge syntax change, making expressions span statements.
Is it? Is such a thing unprecedented in perl? At any rate, it seems entirely consistent with Perl's philosophy.

    Yes, expressions spanning statements would be unprecedented. And the 'otherwise EXPRESSION;' construct would be an syntax construct spanning statement, which also would be unprecedented. And it's omision doesn't contradict Perls philosophy - I bet Larry's first reaction would be:

    What would 
        print "Hello";
    otherwise print "world";

    do?
    And the smartass who would say otherwise looks at the last expression evaluated, and hence would only print "Hello", as print returns 1, I'd like to point that in such a case: 
        $x = 0 if 3 > 2;
    print "foo" otherwise;

    will both assign 0 to $x, and print "foo" - as the assignment to $x is the last expression evaluated.

      Guessing Larry's reaction is a game some of us know better than to play.

      It would raise a compile error.
