/me waits for tye to rebut this ;-)

Anyway, I agree on both the spanning statements and the usability of unless. To me, unless is way better than "if not $foo". However, anything more complex is often easier to write and read as an if: 

  ... unless $foo and not $bar->baz()

Switch that around to if, and it's easier to parse, I think. 
  ... if not $foo or $bar->baz()

Still not easy, but I think that's an improvement of at least half a step.

Back to the otherwise statement. Here's just something to throw out there, more to provoke thought than as a serious suggestion. Rather than separating two statements, what would you think of: 

  $a if $b, otherwise $c;

[download]
Arguably, it's a single statement still. I think I still prefer the full if ($b) { $a } else { $c } version. But at least it deals with the "span statements" issue. Somewhat.
