Ruby block code in haml

The code below is working

-@items.each do |item|
 %tr
  %td
   =item.quantity
   times
  %td= item.product.title
 end

However I want to use { } instead of do ... end. Is it possible?

-@items.each { |item|
 %tr
  %td
   =item.quantity
   times
  %td= item.product.title
 }

For some reason it throws an exception. What did I do wrong?
