LISP: nil to variant...

Can somebody explain this:

(vlax-safearray->list (vlax-safearray-fill (vlax-make-safearray vlax-vbvariant '(0 . 1)) '(nil nil))) ; => (#<variant 11 0> #<variant 11 0>)

(vlax-make-variant nil) ; => #<variant 0 >

Why is nil translated differently? Is it logical, compatible or ...

Thanks in advance.

Regards, Roy.

    Obviously it is an inconsistency bug.

    In ACAD 2008 and 2010 the line

    (vlax-safearray->list (vlax-safearray-fill (vlax-make-safearray vlax-vbvariant '(0 . 1)) '(nil nil)))
    returns

    (#<variant 0 > #<variant 0 >)

    Did you file a support request?

    Dear Roy, Dear Stephan,
    many thanks for the hints !
    Of course, the results are not consistent and not Acad compatible ...
    I will fix the problem ... and will keep you updated here.
    Many greetings, Torsten

    Stephan and Torsten thank you both for clearing this up. I'm not yet very experienced with all this so called "visual" stuff, so I was hesitant to call it a bug and report it as such.

    Regards, Roy.
