I found something like this in a blog post. I agree with the post subject, just don't understand why the author choose the following idiom

Raw

case.rb

	foo = case value
	when nil
	NullObject.new
	else
	value
	end

por que não:

foo = if value
  value
else
  NullObject.new
end

ou

foo = value.nil? ? NullObject.new : value

ou ainda

foo = value || NullObject.new

foo = value || NullObject.new

É bem melhor :D
