|I could either submit a patch which changed all the {id}'s to

Since `#{id}' in the quoted code suppose number to be interpolated,
changing Symbol.to_s to return "julian" does not solve the problem.

I changed once() like the following, which runs fine on older Ruby too.

    def once(*ids)
      for id in ids
	p id
	module_eval <<-"end;"
	  alias_method :__#{id.to_i}__, #{id.to_i}
	  def #{id.id2name}(*args, &block)
	    def self.#{id.id2name}(*args, &block); @__#{id.to_i}__ end
	    @__#{id.to_i}__ = __#{id.to_i}__(*args, &block)
	  end
	end;
      end
    end
