Hi,

My use case is like I stated on the start of my message. I created a 
function that takes a block, transforms the output of what's inside the 
block, and outputs the result. I came up with something like this:

def form_label(label)
  block = yield([])
  block = block.join("\n") if block.is_a?(Array)
  "#{label}: #{block}"
end

form_label 'example' do |a|
  a << text_field_tag ...
  a << link_to ...
  a << 'something more'
end

I didn't want to do something special inside the block (more than just 
calling functions, or returning strings), as I thought "yield" would 
capture everything that's inside it... which doesn't make sense once I 
think more about it :)
