Hi Eric

thanks, after some fiddling I was able to make it work...

But do I get it right?

The snippet has to be explicitely named, I can't tell the hyperlink just to
take the next block?

Before I start trying it, is it theoretically possible to write an on
ob-multiline.el which parses the following lines?

I.e. is the current "point" known at execution time?

Out of curiosity, the manual says

> The org-babel-load-languages controls which languages are enabled for
evaluation (by default only emacs-lisp is enabled).

Is it done out of security reasons? Cause it wouldn't be a problem to start
a  process via elisp and (shell-command ...)

Next question:

shell-command normally prints the stdout into the minibuffer, but
org-hyperlink executions overwrite it with the return code.

Is this behaviour configurable?

Thanks for the help
  Rolf

PS: ob-perl.el says
-----
(defun org-babel-perl-initiate-session (&optional session params)
  "Return nil because sessions are not supported by perl"
nil)
------
What is meant with supporting sessions? IIRC do packages like sepia.el fork
a perl process allowing bidirectional communication with emacs.

Or what kind of extra support is neccessary here?
