Hamlet, probably not that it throws such an exception, I think 
Seriously I would expect the same behaviour than calling 'abc'.next(), which is 'abd' and increments the last character whereas 'abc' + 1 results in 'abc1' and is not the same than 'abc'.next()

what is the expected output of 'abc'++
are you expected it to evaluate the same as 'abc' + 1 ?
