Subject: Re: How to pass a hash as a param to a method called through eval?

Thanks again, yermej's suggestion actually worked out.  I've now got
send doing exactly what I wanted to accomplish.

Going into my thinking on this problem, I knew I wanted dynamic
execution, and being relatively new to ruby, thought that eval would be
the right tool.  Wasn't aware of send.  Great thing is it caused me to
look up the Object and see all the cool things it can do for me.

So my original question probably should have been, "is eval even the
right tool for this?".  Of course, that's not always obvious considering
there's always more than one way to do something in ruby.
