I like the proposed syntax! I also think that C<keys @array> would be
useful, I often use arrays as integer-based lookups (like for database
results, primary keys and field names). To loop through a list like that,
where the array doesn't start at 0, nor has a consistent increment, I
practically have to kloodge the darn thing, doing:

   $i = 0;
   foreach(@array) {
       $i++;
       ...
   }

or:

   for($i = 0; $i <= $#array; $i++) {
	next unless $array[$i];
        ...
   }

this:

   while(($index, $value) = each(@array)) {
       ...
   }

Seems much more elegant, although maybe we should stick to for* commands
for arrays.
