I think even in Python it is sometimes necessary to increment things (as 
the OP did).

But I had in mind not implementing ++ and --, but detecting them and 
issuing a warning, so forcing someone to type "+ +" or to use 
parentheses, which is unlikely to be much of an imposition as how often 
are two unary pluses going to be used together?
