Checking in Lisp if a given symbol has its original value

[Bruno Félix Rezende Ribeiro]

What’s the canonical way of checking if a given symbol has its
original value, as reported by ‘describe-variable’?

I’ve come up with:

#+BEGIN_SRC elisp
  (defun standard-value-p (symbol)
    "Return non-nil if SYMBOL has its original value."
      (equal (eval (car (get symbol 'standard-value)))
             symbol))
#+END_SRC
