9.1.4.2.4 Associating a Restart with a Condition
A restart can be "associated with" a condition explicitly
by with-condition-restarts, or implicitly by restart-case.
Such an assocation has dynamic extent.
A single restart may be associated with several conditions
at the same time.
A single condition may have several associated restarts
at the same time.
Active restarts associated with a particular condition can be detected
by calling a function such as find-restart, supplying
that condition as the condition argument.
Active restarts can also be detected without regard to any associated
condition by calling such a function without a condition argument,
or by supplying a value of nil for such an argument.
