Hi Nicolas,

At the moment org-babel believes that any time it sees a valid source
block name surrounded by <<>> characters it is responsible for expanding
them.  Is there a reason that you are abusing this syntax?  It looks as
though you are trying to setup multiple levels of tangling like
org-babel -> noweb -> source.

If you can make a good case for why the behavior you describe should be
supported then we could try to add it behind something like a

#+srcname: b
#+begin_src emacs-lisp :noweb no
  <<a>>
  (b)
#+end_src

header argument, but at first blush the option seems to present too much
opportunity for confusion.  Maybe I'm missing something.

Thanks -- Eric
