And to make it even weirder (from `dash.el'):

    (defalias '-first-item 'car

      "Return the first item of LIST, or nil on an empty list.")

    (subr-arity (symbol-function '-first-item))  =>  (wrong-type-argument subrp car)

This at least can be made to work by using indirect-function instead of symbol-function.
