I really like this section.  Clean, powerful, limpid, compatible: it is
what Scheme deserves.

I retain doubts however regarding the rewind behavior of `guard'.
Though I can see why you would want to do it, rewinding is not something
that I want to happen while I'm handling errors.  Better to have `guard'
procedures run the predicates in the dynamic extent of the `raise', and
then jump down to the body to handle it, if the predicates returned a
true value.
