Easy enough to do as is with a block, provided the package author simply
provides a "yield self if block_given?".

e.g.

class Foo_Widget
   attr_accessor :height, :border, :bgcolor
   def initialize
      yield self if block_given?
   end
end

o = Foo_Widget.new{ |f|
   f.height  = 10
   f.border  = 2
   f.bgcolor = "red"
}

p o -> #<Foo_Widget:0x28ac140 @height=10, @bgcolor="red", @border=2>
