I consider it a mistake to divide conditions into continuable and
non-continuable.  A condition represents a particular state of affairs,
whereas it is the circumstances in which an exception is raised
which should determine whether it makes sense to go on.  This is captured
by the raise and raise-continuable procedures.

Alas, no.  I have dealt only with guard-style systems with termination
semantics.
