It turns out that, at least for my use case, completely reevaluating the
whole expression in fact DTRT -- see the attached file. Admittedly,
elegant it isn't, and AFAIK this is virtually never done (I guess that's
why it didn't occur to me when I asked the above question) -- but other
than inelegance, is there a problem with doing this?
