Devil's advocate argument for having the case statement in Ruby

gistfile1.rb

case some_value
  when 1..10
    "do some stuff here"
  when 11..20
    "do something else here"
  else
    "out of range"
end

# compared to

if 1..10.include?(some_value)
  "do some stuff here"
elsif 11..20.include?(some_value)
  "do something else here"
else
  "out of range"
end
