--- Comment #4 from Miguel Barao <miguel.barao at gmail dot com> 2012-05-17 09:42:48 UTC --- There was a misunderstanding between associativity and operator evaluation order in the original bugreport. I now understand that the language does not specify the evaluation order of an operator, and is bad a practice to depend such behavior. Still, I would like to add that expressions like - f( ) + f( ) and - ( f( ) - f( ) ) produce different evaluation orders, and therefor different results, when f( ) has side effects.
