Subject: Re: how to compare two object instances? is "m1.to_yaml.eql?(m2.to_yaml)" 	a good way?

actually I just saw this posted on
"http://www.reddit.com/r/ruby/comments/9540i/ruby_developers_make_sure_you_define_eql_and_hash/"
that might be good...


    def eql?(other)
        return false unless other.class == self.class
        return false unless other.instance_variables == self.instance_variables
        self.instance_variables.each do |var|
            self_var = self.instance_variable_get(var)
            other_var = other.instance_variable_get(var)
            return false unless self_var.eql?(other_var)
        end
        true;
    end
