    d'après la doc, 8.4.1 except clause :

    When an exception has been assigned using as target, it is cleared at the end of the except clause. This is as if

    except E as N:
 foo

    was translated to

    except E as N:
 try:
 foo
 finally:
 del N

    This means the exception must be assigned to a different name to be able to refer to it after the except clause. Exceptions are cleared because with the traceback attached to them, they form a reference cycle with the stack frame, keeping all locals in that frame alive until the next garbage collection occurs.
