Subject: Re: Any way to evaluate blocks using an arbitrary Binding?

Robert,

I was already aware of instance_eval (have to look up class_eval) used 
in this manner (possibly from another of your very useful postings), but 
had wondered if there was a more general way of affecting the execution 
environment. Oh well.

Thanks,
Ken
