Defining functions within `condition-case'

[Jean Louis <bugs@gnu.support>]

Is there any argument against following notion:

;; -*- lexical-binding: t; -*-

(condition-case my

    (defun my-2-hello ()
      (message "I am `my-hello'"))
      
  (error (message "%s" my)))

(my-2-hello) ➜ "I am ‘my-hello’"

I am testing it, it seems that it works.

The reason for this is website application development. I would like
to ensure that, in case of any errors, I can access a function to
inform me what went wrong. These errors should be presented over an
HTTP connection, and I do not intend to inspect them through Emacs
directly.
