No, everyone does most assuredly not agree on readability when it comes to case statements. Flat case reads better, and indenting it would be like indenting "elsif" and "else" in an else statement.
yeah, even more, taking the example from the style guide, if lines are short enough, I love doing:
case
when song.name == 'Misty' ; puts 'Not again!'
when song.duration > 120 ; puts 'Too long!'
when Time.now.hour > 21 ; puts "It's too late"
else
song.play
end
even more, for simple if/elses, many times I do:
if member.coding_style.vertical_align?
then friends << member
else member.show_example(code)
end
