[O] Hidden named blocks.

[abonnements]

Hello,
    I would like to know if there is, or if it is simple, to have a 
"#+STARTUP: hideblocks" like option which allow to fold named blocks 
leaving only the #+name:

Example
#+name: test
#+header: :var foo=10
#+begin_src python
...
#+end_src

is displayed on the opening of the file folded this way
#+name: test ...

instead of
#+name: test
#+header: :var foo=10
#+begin_src python ...

Ta.
Thierry
