s-upper-camel-case error on modify-syntax-entry

[xcwen]

config "_" as word :

 (modify-syntax-entry ?_ "w" c-mode-syntax-table) 

(s-upper-camel-case "aa_bb") will get "Aa_bb"

do this is ok?!

(defun my-s-split-words (s)
  "Split S into list of words."
  (declare (side-effect-free t))
  (s-split
   "[^a-zA-Z0-9]+"    ;; old: "[^[:word:]0-9]+"
   (let ((case-fold-search nil))
     (replace-regexp-in-string
      "\\([[:lower:]]\\)\\([[:upper:]]\\)" "\\1 \\2"
      (replace-regexp-in-string "\\([[:upper:]]\\)\\([[:upper:]][0-9[:lower:]]\\)" "\\1 \\2" s)))
   t))
