{{{ CL-USER> '(2 . 5) (2 . 5) CL-USER> '(2 . 5 . 5) (2 . 5) CL-USER> (equal '(2 . 5) '(2 . 5 . 5)) T

while other implementations give me an error when i type '(2 . 5 . 5) it's a bug or ANSI CL allows this? }}}

According to Pascal J. Bourguignon's reading if the CLHS <http://article.gmane.org/gmane.lisp.armedbear.devel/3455>, ABCL should signal a READER-ERROR (or possibly an ERROR) to return to ANSI conformance
