[Python-ideas] An unambiguous way of initializing an empty set and dictionary

Currently: l = [] # new empty list t = () # new empty tuple s = set() # new empty set (no clean and consistent way of initializing regarding the others) <<< d = {} # new empty dictionary Possible solution: s = {} # new empty set d = {:} # new empty dictionary (the ":" is a reference to key-value pairs) Current workaround at least for consistency: l = list() # new empty list t = tuple() # new empty tuple s = set() # new empty set d = dict() # new empty dictionary However, it doesn't feel right to not be able to initialize an empty set as cleanly and consistently as lists, tuples and dictionaries in both forms.
