Subject: 'each' returning array

A newbie problem:

Is there a way to transparently accumulate expresions evaluated within
a block into an array, without introducing an external variable? For
example, I'd like to write something like this:

"HAL".each_byte__returning_array {|x| (x+1).chr} .collect # more processing

...instead of this:

l=[];  "HAL".each_byte {|x| l<< (x+1).chr};  l.collect #...

One of my first impressions with ruby was the surprise that each*
method family doesn't return such accumulated arrays just for method
chaining.

Am I thinking totally non-rubyish? ;-) If so, please show me the Right
Way..
