So you're not creating a class, really. You're creating an instance of
already-defined classes. Right?

You can smash those down to one line and get rid of your holder
variable, if you like:

def create_thing var
  sub = Object.const_get(type[var]).new
  puts sub.class
end

I'm not a huge fan of holder variables, myself, but your mileage may
vary, of course.
