As the other guys have said, RubyGarden have the following implementation:

   def get_class(name)
     name.split(/::/).inject{|parent, child| parent.const_get(child) }
   end

I actually have two questions regarding this implementation:

   1)  Is `/::/' faster than `"::"'?
   2)  Isn't it more appropriate to call #to_str on `name'? I.e.
         name.to_str.split(...


Cheers,
