This one's our fault. That should be
#+begin_src python
return x*x
#+end_src
I've changed it on Worg.

OK, that works for me.

That's not correct usage of #+function; you wanted #+lob: / #+call:
there.
There are two sets of synonymous terms. *Within* each of these sets, the
terms are synonymous:
{#+function,#+source,#+srcname}
{#+lob,#+call}
My edited version of your input is below.
Hope that helps, do get back to the list if you have further questions.
