In Common Lisp exceptions are called conditions and error is a subtype of
condition. However whether a debugger appears in case of an unhandled
condition is not determined by the type of the condition, but by whether
the condition was signalled with the function #'signal or with the function
#'error. The latter establishes a default handler that opens the debugger.
