The message is a little confusing, but the error comes from the fact
that literal_eval permits a very few legal operations, and calling a
function isn't one of them. So when you try to evaluate the "literal"
that you've given it, you get back an error saying that a Call is
'malformed'. More accurate would be to say that it's not permitted.
