Type Checking in Perl: Gaaaack

        while (<>) {
          $total += $_;
        }

        @a = (1, 3.1416, "A painted lotus flower");

        @a = localtime();
        $s = localtime();

        print ;

        if (@a) { ... }
        $s = @a;

        $a[100000] = 'big!';
        $h{nosuchkey} = 'It means "to chop"';

Probably none of these would work right.

Conclusion:

You can't make a hot fudge sundae with mashed potatoes instead of ice cream, either.
