That's true, of course.  Lambdas are an exception in Emacs Lisp and
CL, though.

    (info "(elisp)Lambda Expressions")

    In Emacs Lisp, such a list is valid as an expression--it evaluates
    to itself.  But its main use is not to be evaluated as an
    expression, but to be called as a function.

I stumbled upon this issue a few times already.  So did others.

IMO the info node I referenced above should mention this.
