+### Setup evaluation commands using prefix arguments
+
+Instead of bothering setting up different key bindings for elisp evaluation
and inspection, it can be handy to have both in the same command, and use
prefix arguments to differenciate, like this:
+
+```emacs-lisp
+
+;;;###autoload
+(defun inspector-eval-expression (arg)
+ "Like `eval-expression', but also inspect when called with prefix ARG."
+ (interactive "P")
+ (pcase arg
+ ('(4) (let ((current-prefix-arg nil))
+ (call-interactively #'inspector-inspect-expression)))
+ (_ (call-interactively #'eval-expression))))
+
+;;;###autoload
+(defun inspector-eval-last-sexp (arg)
+ "Like `eval-last-sexp', but also inspect when called with prefix ARG."
+ (interactive "P")
+ (pcase arg
+ ('(4) (inspector-inspect-last-sexp))
+ (_ (call-interactively #'eval-last-sexp))))
+```
+
+Setup key bindings:
+
+```emacs-lisp
+(define-key global-map [remap eval-last-sexp] #'inspector-eval-last-sexp)
+(define-key global-map [remap eval-expression] #'inspector-eval-expression)
+```
+and then use `C-u C-x C-e` and `C-u M-:` as alternatives to `eval-last-sexp`
and `eval-expression`.
