Update: - fixed screwed-up formatting within code tags.

Just an observation regards style. (And please don't get me wrong - this is just an observation, not a critisism - each to their own :)

I find it interesting that both yours and Liverpole's answer use a similar layout style for the ternary. That is - to break the line after an operator.

This of course goes against what is recommended by TheDamian in PBP (pp. 27-29 & 121-123). Personally, I prefer his recommended style, and I would have written your second example like so: 

$result = ($major_length == 4800)  ? 18
        : ($major_length == 8552)  ? ($val == 4   ? 33
                                   : $val == 1    ? 18
                                   : die "not handled")
        : die "not handled";

To me, this is more readable - it looks more like a "table", and it's more obvious that there is some nesting. Also, having an operator at the start of a line makes it much more obvious that it's a continuation of the previous line.

Cheers,
Darren :)
