[Python-ideas] Using 'with' with extra brackets for nicer indentation

Hello everybody, today I tried to open four files simultaneously by writing with ( open(fname1) as f1, open(fname2) as f2, open(fname3) as f3, open(fname4) as f4 ): ... However, this results in a SyntaxError which is caused by the extra brackets. Is there a reason that brackets are not allowed in this place?
