One method is to use method_missing.

  module ClassMethods
    def method_missing(id, *args, &block)
      if /\A[a-z][A-Za-z_0-9]*\z/ =~ name = id.to_s
        classes = []
        constants.each do |n|
          if name.casecmp(n).zero? and Class === (c = const_get(n))
            classes << c
          end
        end
        if classes.size == 1
          return classes.first.new(*args, &block)
        end
      end
      super
    end
  end
