with-condition-restarts
condition-form restarts-form {form}{*}
=> {result}{*}
condition-form---a form; evaluated to produce a condition.
condition---a condition object resulting from the evaluation of condition-form.
restart-form---a form; evaluated to produce a restart-list.
restart-list---a list of restart objects resulting from the evaluation of restart-form.
forms---an implicit progn; evaluated.
results---the values returned by forms.
First, the condition-form and restarts-form are evaluated in normal left-to-right order; the primary values yielded by these evaluations are respectively called the condition and the restart-list.
Next, the forms are evaluated in a dynamic environment in which each restart in restart-list is associated with the condition. See section Associating a Restart with a Condition.
section restart-case [Macro]
Usually this macro is not used explicitly in code, since restart-case handles most of the common cases in a way that is syntactically more concise.
