Safe and robust S-Expression reader. Useful to read from unfailthfull stream/socket.

NULL-PACKAGE aims to be used for static analyzing rather than security. If you want more strict one for security reason, SAFE-READ is recommended.
(with-input-from-string (s "hoge")
(read-with-null-package s))
=> #:HOGE
For details, see spec file.
If NIL (the default), every symbols are uninterned.
If T, only broken symbols are uninterned.
(let ((*only-junk-p* t))
(with-input-from-string (s "(car (cdr (list a b no-such-package:c)))")
(read-with-null-package s)))
=> (CAR (CDR (LIST A B #:C)))
If *ONLY-JUNK-P* is the list of package designators,
the symbol satisfies *TARGET-SYMBOLS* are only interned.
(defpackage test (:use :cl) (:export car cdr))
(let ((*terget-symbols* :external) ; The default though.
(*only-junk-p* '(:test)))
(with-input-from-string (s "(car (cdr (list a b no-such-package:c)))")
(read-with-null-package s)))
=> (CAR (CDR (#:LIST #:A #:B #:C)))
In fact, ideal syntax was like below.
(let ((*package* (find-package :null)))
(with-input-from-string (s "hoge")
(read s)))
But there is no portable way to set default reader to readtable.

When NIL, all symbols are uninterned except boolean and keyword.
When list, included package’s symbols which satisfies TARGETP are not uninterned.
When T, broken notation only uninterned.
