Yes I'd found the dictionary form in the docstring, but didn't know
that it took the python variable rather than the symbol name (if you
see what I mean), and so was still having the same problem.
The docstring suffers from the fact that all the python variables have
the same name as the symbol they are representing so you can't tell
which is meant to be used in each form.
Thanks.
