Thanks for the suggestion, Michael. I think it would work, but
the function I'm aliasing to is `symbol-value', and I would feel
slightly uncomfortable to insert an intermediate function which
would have to either call `symbol-value' or be redefined to be
it. Fortunately, I hadn't used defsetf inside a conditional
more than a couple of times, and for those it was easy to devise
adequate workarounds (once I understood what the problem was).
For the future, I have resolved to use `defsetf' only at top
level.
