The elisp code for the below pseudo code
if "the emacs version is less than 23.1.x"
do
something
else
something-else
is written as
(if (or (< emacs-major-version 23)
(and (= emacs-major-version 23)
(<= emacs-minor-version 1)))
(setq color-theme-is-global t)
(color-theme-initialize))
How to optimize the above code, so that the “emacs-major-version” is not referenced twice.
No need for that, there’s
version<=andemacs-version
