Nice suggestion, thanks a lot. According to the documentation, I can
"call" functions from the library of babel from anywhere, but when I try
this:

#+begin_src org
#+name: test
#+begin_src perl
   for (my $i = 0; $i != 10; ++i) {
        print "hello, world!\n";
   }
#+end_src

#+call: echo(test)
#+end_src

I get a "org-babel-ref-resolve: Reference 'echo' not found in this
buffer".

Do I need to do something special to load the library?
