The way I see it, the following should hold
empty_flag = RegexFlag(0) any_case = RegexFlag.IGNORECASE any_case_on_any_line = RegexFlag.IGNORECASE | RegexFlag.MULTILINE
any_case in empty_flag is False any_case_on_any_line in empty_flag is False
empty_flag in any_case is False empty_flag in any_case_on_any_line is False
The latter two defy all logic. Please don't. Your 'in' operator clearly means "is a subset of", and the empty set emphatically is a subset of all sets (this is the most basic mainstream set theory you can think of). -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-c...
