Yep, that will give me something similar:
#+name: val1
#+BEGIN_SRC org :exports none
foo
#+END_SRC
#+name: val2
#+BEGIN_SRC org :exports none
bar
#+END_SRC
#+BEGIN_SRC org :noweb yes
Currently this gives me ~<<val1>><<val2>>~ indeed!
#+END_SRC
Compared to multiline macros, though, having to (re)define bunch of src
blocks for variables does seem like an overkill.
BTW, does anyone know how I could enforce the standard
Org-interpretation of '~' in the resulting, exported Org.
