-** A better custom variable setter
-Something people often forget about custom variables in Elisp is they
-can have a custom setter that will run some code if we set the
-variable properly with ~customize-set-variable~, so ~setq~ shouldn’t be
-the user’s choice by default. But repeatedly writing
-~customize-set-variable~ can get tiring and boring. So why not take the
-best of both world and create ~csetq~, a ~setq~ that uses
-~customize-set-variable~ under the hood while it keeps a syntax similar
-to the one ~setq~ uses?
-#+begin_src emacs-lisp
-(defmacro csetq (&rest forms)
-  "Bind each custom variable FORM to the value of its VAL.
-
-FORMS is a list of pairs of values [FORM VAL].
-`customize-set-variable' is called sequentially on each pair
-contained in FORMS. This means `csetq' has a similar behaviour as
-`setq': each VAL expression is evaluated sequentially, i.e. the
-first VAL is evaluated before the second, and so on. This means
-the value of the first FORM can be used to set the second FORM.
-
-The return value of `csetq' is the value of the last VAL.
-
-\(fn [FORM VAL]...)"

-  (let (sexps)

-I first got inspired by [[https://oremacs.com/2015/01/17/setting-up-ediff/][this blog article]] (archived article, just in
-case) but it seems the code snippet no longer works properly, so not
-only did I have to modify it to make it work with an arbitrary amount
-of arguments (as long as it’s pairs of variables and their value), but
-I also had to make the code simply work.
