It would only be defined on the span, unless you added the "global"
keyword.  This isn't what I meant, though.

I would write <span tal:replace="nothing" tal:define="call
here/do_stuff" /> ("call" is just a dummy variable), but the idea is the
same.  This is pretty much what I was suggesting, except that I would
use a Python Script, not a DTML Method.
