Yeah, hmm. Maybe it's not such a great idea to remove "error"
everywhere just to cover some obscure corner case. Just mentioning
that corner case specifically should be enough to get the idea across.
A handler is applicable to an error if CONDITION-NAME is one of the
-error's condition names. A CONDITION-NAME of t applies to any error
-symbol. If an error happens, the first applicable handler is run.
