Well ...

(and (eq nil '())
     (symbolp '())
     (listp '())
     (atom '())
     (not '()))

[Not to mention (car nil) => nil.]

It's funny that nil never seems to stop being fodder for an
argument ... 

In Emacs Lisp nil/'() is some sort of a Trickster deity in the
pantheon of data types.

Personally I like this a lot and I find it very convenient. YMMV, of
course. Yet, IMO this “overloading” just emphasizes the fact that
lists are a prominent data type.

Hmm … actually C with its NULL/0 isn't so much different here.
