Based on the code snippets at
<https://github.com/flakyhermit/emacs.d/blob/6b488895071e980433facf648f482974526d6a13/init.el#L22>,
I figured out the following solution with `straight-use-package'
command:

(defvar package-list)
(setq package-list '(
       flycheck lsp-mode dash posframe
       s ein smartparens valign
       multi-term
))

(mapc (lambda(package-name)
(straight-use-package package-name)) package-list)

But I still don't know the corresponding implementation with
`use-package' command.
