Yep, that will give me something similar:

#+name: val1
#+BEGIN_SRC org :exports none

#+name: val2
#+BEGIN_SRC org :exports none

#+BEGIN_SRC org :noweb yes
  Currently this gives me ~<<val1>><<val2>>~ indeed!

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.
