This ...

["H", "A", "L"].collect { |x| x.succ }.each{|b|
      puts "I got #{b}"
 }

... produces

I got I
I got B
I got M

However, this ...

["H", "A", "L"].each { |x| x.succ }.each{|b|
      puts "I got #{b}"
 }

.. gives:

I got H
I got A
I got L

So, my question is, what exactly is the difference between 'each' and
'collect'?
Why doesn't the 'each' block return the value of the last expression?
