Not exactly. The way I figure it, the best way to achieve this with
unary plus is to ast.parse it (as we currently do) and then modify
the parse tree. That works but it's kind of messy.<br>

My main objection to this notation is that that set objects <i>don't
support +.</i>Â The union operator for sets is |.<br>

I used the tokenize module to tokenize, modify, and untokenize the
converter invocation. Works fine. And since augmented assignment
is (otherwise) illegal in expressions, it's totally unambiguous. I
think if we do it at all it should be with that notation.<br>
