If member? is allowed to use non-discrete comparisons for integers,  
then it should probably also do them for ranges of strings. Right now

('a'..'z').member?('aa')

returns false, because 'aa' is not in the set 'a', 'b'...'z'. But,  
logically, if (1..3).member?(1.5) is true, then the string range  
should return true as well, as 'a' <= 'aa' <= 'z'.
