try this:

    def test( obj )
        case obj
           when Array then puts "Array"
           when Hash  then puts "Hash"
           when Class then puts "Class"
           else puts "ugh"
        end
    end

Unfortunately the behavior above is still annoying; in this case you
have an object to work with, but I've run into a number of cases
where I have only a class, and I just have to use a big "if" block.
