Subject: Re: Newbie Problem with Shell#transact

OK.  That works, but the more important question is, "Why?"  Is there a
general principle I can apply here?  Should it be considered a bug?  At
least for me, it violates the Principle Of Least Surprise, but my Ruby
intuition is not yet well trained.

Thanks,
Xandy
