Sublime Text 2's “Goto Anything” (or instant search) for Emacs?

Question

I tried out Sublime Text 2 recently, and I found Goto Anything superbly useful for navigating source code (Ctrl-P file@symbol seems to work really well). Is there something simi

for emacs I customize and modify this solution (for use install helm):

(defun helm-occur-from-point (initial-value)
  "Invoke `helm-occur' from point."
  (interactive)
  (let ((input initial-value)
        (bufs (list (buffer-name (current-buffer)))))
    ;; (isearch-exit)
    (helm-occur-init-source)
    (helm-attrset 'moccur-buffers bufs helm-source-occur)
    (helm-set-local-variable 'helm-multi-occur-buffer-list bufs)
    (helm-set-local-variable
     'helm-multi-occur-buffer-tick
     (cl-loop for b in bufs
              collect (buffer-chars-modified-tick (get-buffer b))))
    (helm :sources 'helm-source-occur
          :buffer "*helm occur*"
          :history 'helm-grep-history
          :input input
          :truncate-lines t)))

(defun get-point-text ()
    "Get 'interesting' text at point; either word, or region"
    (if mark-active
        (buffer-substring (mark) (point))
      (thing-at-point 'symbol)))
  (defun helm-occur-1 (initial-value)
    "Preconfigured helm for Occur with initial input."
    (helm-occur-from-point initial-value))
  (defun bk-helm-occur ()
    "Invoke helm-occur with initial input configured from text at point"
    (interactive)
    (helm-occur-1 (get-point-text)))
  (global-set-key (kbd "M-s-o") 'bk-helm-occur)

primary it based on @see https://news.ycombinator.com/item?id=6872508 but on last helm versions not work but fixed with my changes (just copy/paste from some internal helm modules)
