I'm falling a little short of understanding how you're using the term 'express', but the -p switch is very cool!

quoth the 1st Camel, on pg. 96, and the 2nd Camel, on pg. 99: <it>

for ($I = 1; $i < 10; $i++) {
      ...
}

is the same as

$i = 1;
while( $i < 10) {
     ...
}
continue {
     $i++;
}

Personally, I like the symmetry it gives the language.
(if only it had an elswhile clause to complete the symmetry...)

An elsewhile would add symmetry but wouldn't a meanwhile be more fun?:)

Thanks for the follow-up,
