Executing a block in another context isn't very readable. Ara's
example is not the same as your situation. His situation is an
example of a DSL, whereas your situation is just plain Ruby.
So, IMHO, it should be coded in just plain Ruby:

 class Button
   def initialize
     yield(self)
   end
 end

 button = Button.new do |b|
    b.caption = 'Click Me'
 end

Now it's obvious (by reading, not by knowing) what the block
does.
