Subject: Re: Newbie question: Small blocks

You can type any block with the  { } or the do..end way. You don't have 
to have the pipes, but without them you don't have a way to pass items 
of your collection into the block. So for example

array.each { puts "HELLO" } <--- no pipes, but no data

The only thing I can think of where you would have seen the & would be 
something like

irb(main):001:0> (0..5).each { 0 & 5 }
=> 0..5
irb(main):002:0>
