Er...not quite, because (in his example) he has class objects, not
instances.

[Kernel,String,Object].each do |klass|
case klass
  when Kernel
    puts "I'm doing stuff with object Kernel"
  when String
    puts "I'm doing stuff with object String"
  when Object
    puts "I'm doing stuff with object Object"
  end
end
#=> I'm doing stuff with object Kernel
#=> I'm doing stuff with object Kernel
#=> I'm doing stuff with object Kernel


ebeard, in reality are you trying to handle class objects in your case
statement, or do you have instances of that class that you're trying to
determine the class of?
