Hi Rainer,

I just pushed up a new hook `org-babel-post-tangle-hook' which can be
used to run activities in tangled code files immediately after tangling.
I believe the following can be used implement the feature you described
with this hook.

(add-hook 'org-babel-post-tangle-hook
          (lambda () (ess-load-file (buffer-file-name))))

Best -- Eric
