I have 9 317 lines in 165 files ...

On the contrary, that's good for all of us!

But on the whole, it is not a sane situation. What we should
have is a set of libraries that have very basic and
self-explicatory names, then it would be so easy to find out
if some functionality is already available - and if not, where
to add it ...

For example, I'd like to have a math library for thing like
the blow Elisp, which I have in my own Elisp at the moment ...

(defalias '**   #'expt)
(defalias 'ceil #'ceiling)

(defun // (nom denom)
  (/ nom denom 1.0) )

;; (/  8 256) ; 0 *oups*
;; (// 8 256) ; 0.03125

(defun mean-value (vs)
  (let*((sum  (apply #'+ vs))
        (mean (/ sum (length vs) 1.0)) )
    mean) )

(defun percent (nom &optional denom str)
  (or denom (setq denom 1))
  (let ((perc (/ nom denom 0.01)))
    (if str
        (format "%.1f%%" perc)
      perc)))

;; (percent 0.25)           ; 25.0
;; (percent 50 75)          ; 66.66 ...
;; (percent (// 1 2) nil t) ; 50.0%
;; (percent 1019 22 t)      ; 4631.8%
