I don���t think #exclude? really conveys what���s being done very well.
Yes, ���exclude��� is the antonym of ���include���, but the meaning of %[a b
c].include? x is very natural, whereas %[a b c].exclude? x isn���t.
Does it mean that %[a b c] contains the elements that should be
excluded and is x among them, or is x not included among the elements
of %[a b c]?
